A high school athletic department bought 40 soccer uniforms at a cost of $3000. After soccer season they returned some of the uniforms but only received $40 per uniform. What was the difference between what they paid for each uniform and what they got for each return?

I have attached a picture which clearly explains.

Yes due to the fact that additive inverse is the oppsite. so she runs up +4 and runs down -4.

ANSWER:

C - $7.50

REASONING:

If I placed $1,000 in a savings account with an interest rate of 4.5% per month, I would earn $45 in one month.

$1000x.045=$45

If I placed $1,000 in a savings account with an interest rate of 3.75% per month, I would earn $37.50 in one month.

$1000x.0375=$37.50

I would earn an additional $7.50 in one month by placing the money in the savings account with the 4.5% interest rate.

$45-$37.50=$7.50

The question involves understanding multiplication and division principles. Section A has 180 seats in total (12 rows * 15 seats). Section B, having the same total number of seats but only 10 rows, would have 18 seats per row.

The question involves the basic principles of mathematics, specifically dealing with multiplication and division concepts. Section A of the theater has 12 rows of 15 seats each, which totals to 180 seats (12 * 15 = 180). As it is stated that Section B has the same number of seats as Section A but only consists of 10 rows, each row in Section B must, therefore, contain 18 seats (180 / 10 = 18).

This is an application of the principle that if a total quantity remains the same, and it is divided into fewer groups, then each group will contain more than before. Therefore, even though Section B has fewer rows than Section A, each row in Section B contains more seats, leading to the same total.

There are 18 seats in each row of Section B.

To find out how many seats are in each row of Section B, let's first calculate the total number of seats in Section A:

Total seats in Section A = 12 rows × 15 seats per row = 180 seats

Since Section B has the same total number of seats as Section A but only 10 rows, we can find out how many seats are in each row of Section B by dividing the total number of seats in Section B by the number of rows in Section B:

Seats per row in Section B = Total seats in Section B / Number of rows in Section B

We already know the total seats in Section B is 180, and the number of rows in Section B is 10.

Let's plug these values into the formula:

Seats per row in Section B = 180 seats / 10 rows = 18 seats

The complete question is-

In a theater, Section A contains 12 rows of 15 seats each. Section B has the same total number of seats as Section A but contains only 10 rows. How many seats are in each row of Section B?

Step-by-step explanation:

The required factorized form of the given expression is y(x - 6)(x + 4), where y is the greatest common factor (GCF).

What is the Factorization?

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original.

We have been given that the expression below as

x²y - 2xy - 24y

We have to determine the factor of the expression 50x + 100

First, we have to find the Greatest Common Factor (GCF).

GCF = y

y Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

y(x² - 2x - 24)

Simplify each term in parentheses.

y(x² - 2x - 4x - 24)

y(x - 6)(x + 4)

Therefore, the required factorized form of the given expression is y(x² - y(x - 6)(x + 4)

The equation that can we use to determine m, the number of marbles per pack is 6(4 1/2 m + 2/3)=629.

The correct answer choice is option D.

Number of packs = 6

Total mass of 6 packs = 629g

Mass of each pack = 2/3 g

Mass of each marble = 4½g

Number of marbles per pack = m

Total mass of 6 packs = Number of packs(Mass of each pack) + Number of packs(Mass of each marble × Number of marbles per pack)

629 = 6(2/3) + 6(4½m)

629 = 6(2/3 + 4½m)

Hence, 6(4 1/2 m + 2/3)=629 is the equation to determine the number of marbles per pack?

Simply multiply all of the fractions with the total number of marbles

48(2/3)(3/4)

Final answer:

There are 24 marbles that are red and have stripes in the box, calculated by first determining the total number of red marbles (32) and then finding three-fourths of those to be striped.

Explanation:

The question involves finding out how many red and striped marbles are in a box, given that two-thirds of the marbles are red and three-fourths of the red marbles are striped. There are 48 marbles in total.

To find the total number of red marbles, we multiply the total number of marbles by two-thirds:

48 marbles × ⅓ (red marbles) = 32 red marbles

Next, to find out how many of the red marbles are striped, we multiply the number of red marbles by three-fourths:

32 red marbles × ¾ (striped marbles) = 24 striped red marbles

So, 24 of the marbles in the box are red and have stripes.

First of all, add 7 to both sides, in order to cancel the -7:

[tex] -7 + 4n +7= 9+7 [/tex]

As we said, the -7 on the left hand side cancels out, while we can add it to the 9 on the right hand side:

[tex] 4n = 16 [/tex]

Now, divide both sides by 4. As before, this is needed to cancel the four on the left hand side and isolate the x, while it is just a normal division between numbers on the right:

[tex] \dfrac{4n}{4} = \dfrac{16}{4} \iff x = 4 [/tex]

Rewrite the equation in an easier way: 4n-7=9

Add 7 to both sides: 4n-7+7=9+7... 4n=16

Divide both sides by 4: 4n/4=16/4

Final answer:

To find 3/8 multiplied by 4/5, multiply the numerators together and the denominators together and then simplify the resulting fraction. The solution in simplest form is 3/10.

Explanation:

To multiply two fractions, you multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together. For the multiplication of 3/8 × 4/5, we multiply the numerators 3 and 4 to get 12, and the denominators 8 and 5 to get 40.

The result of this multiplication is 12/40. However, this fraction can be simplified. We notice that both the numerator and the denominator are divisible by 4. Thus, we divide both by 4 to get the simplest form: 12 ÷ 4 is 3, and 40 ÷ 4 is 10, resulting in the fraction 3/10.

So, 3/8 × 4/5 in its simplest form is 3/10.

Oatmeal - $6

Peanut butter - $5

$6 x 2 = $12

$5 x 2 = $10

$12 + $10 = $22

So Shrina made $22 selling cookie dough.

Hope this Helps!!

To accurately calculate the total amount of money Shrina made from selling the cookie dough, we need to know the price per tub for each type of cookie dough, which are oatmeal raisin and peanut butter.

This information is crucial to compute the answer. Hence, without the prices of the oatmeal raisin and peanut butter tubs, it is impossible to determine how much money Shrina made.

Generally, the calculation would look like this:

The total money earned from selling oatmeal raisin tubs would be the quantity of oatmeal raisin tubs sold multiplied by its price per tub. The same calculation would apply to the peanut butter tubs.

Assuming `oatmeal_raisin_price` and `peanut_butter_price` to be the price per tub of oatmeal raisin and peanut butter respectively, and the quantity sold be represented by `oatmeal_raisin_qty` and `peanut_butter_qty`, the total money made, `money_made` would be:

money_made = (oatmeal_raisin_price * oatmeal_raisin_qty) + (peanut_butter_price * peanut_butter_qty)

The above formula would give us the total amount Shrina made from selling the cookie dough. But without the price of each tub, we can't proceed with the calculation.

15 is 30% percent of 50, so Corey spent 30% of his earnings.

Final answer:

Corey spent 30% of his earnings on the new hat, calculated by dividing the amount spent by the total earnings and then multiplying by 100.

Explanation:

To calculate the percentage of earnings Corey spent on the hat, we should find out what portion of his total earnings ($50) was spent ($15).

We can use the formula for percentage: Percentage Spent = (Amount Spent / Total Earnings) × 100.

So, let's plug in the numbers:

Percentage Spent = ($15 / $50) × 100

= 0.3 × 100 = 30%.

Therefore, Corey spent 30% of his earnings on the new hat.

The item is $365 and is 30% off.

What we need to do first is find 30% of $365. We can do this by multiplying

$365 x 0.3 = $109.5

The discount is $109.5

but what we need to pay is $365 - $109.5 = $255.5

The Sale price is $225. 5

There is not much that can be done to figure out how to write .75 as a fraction, except to literally use what the decimal portion of your number, the .75, means. Since there are 2 digits in 75, the very last digit is the "100th" decimal place. So we can just say that .75 is the same as 7/100.

To find the number of hamburgers sold on Saturday, we can set up an equation and solve for the variable.

Let's represent the number of hamburgers sold as 'x'. We are given that the combined total of hamburgers and cheeseburgers sold is 444, and there were 54 fewer cheeseburgers sold than hamburgers. So, the number of cheeseburgers sold can be represented as 'x - 54'.

The sum of the hamburgers and cheeseburgers sold is 444, so we can write the equation: x + (x - 54) = 444.

Simplifying the equation, we get: 2x - 54 = 444.

Adding 54 to both sides of the equation, we get: 2x = 498.

Dividing both sides of the equation by 2, we get: x = 249.

Therefore, 249 hamburgers were sold on Saturday.

Mrs. Payne can buy the notepads in 5 different ways: 0 packs, 1 pack, 2 packs, 3 packs, or 35 single pads. The number of notepads in each option is either a multiple of 10 or 35.

To find all the different ways Mrs. Payne can buy the notepads, we need to consider two scenarios: buying in packs of 10 and buying as single pads. Let's start with buying in packs of 10. The number of packs Mrs. Payne can buy ranges from 0 to 3, since if she buys 4 packs she would have 40 notepads which is more than she needs. So the different ways she can buy notepads in packs of 10 are 0 packs, 1 pack, 2 packs, and 3 packs.

Next, let's consider buying single pads. If Mrs. Payne buys 35 single pads, she would exactly reach her requirement. So another way she can buy the notepads is by purchasing 35 single pads. In total, there are 5 different ways she can buy the notepads: 0 packs (0 notepads), 1 pack (10 notepads), 2 packs (20 notepads), 3 packs (30 notepads), or 35 single pads.

From the chart, we can observe that each option involves a multiple of 10 notepads except for the last option. This indicates that the number of notepads can be obtained by multiplying a whole number by 10, or in the case of 35 single pads, the count is not a multiple of 10.
