A used book store buys a hardback book for $1.50 and then sells it for $5. Over time, the store sells the same number of books it buys. The store manager can use the equation P(x)=5x−1.5x to determine the store's profit, P(x), where x is the number of books that the store sells. Which statement about the book store is true based on the profit equation?
A.The book store makes a profit of $5.00 for each hardback book that is sold.
B.The book store makes a profit of $3.50 for each hardback book that is sold.
C.The book store makes a profit of $4.50 for each hardback book that is sold.
D.The book store sells each hardback book for $3.50
A used book store buys a hardback book for $1.50 and then sells it for $5. Over time, the store sells the same number of books it buys. The store manager can use the equation P(x)=5x−1.5x to determine the store's profit, P(x), where x is the number of books that the store sells. Which statement about the book store is true based on the profit equation?
Cost Price of book, C.P.=$1.50
Selling Price of book, S.P.=$5
PROFIT=S.P. -C.P.
So, Profit=$5-$1.50=$3.50
So, Profit=$3.50 on each book
Or, we are given P(x)= 5x-1.50x
Or, P(x)=3.50x
For each book, we must divide the profit P(x) by x, that is, number of books
[tex] \frac{P(x)}{x}=\frac{3.5x}{x} [/tex]
[tex] \frac{P(x)}{x}=\frac{3.5*1}{1} [/tex]
[tex] \frac{P(x)}{x}=3.5 [/tex]
So, Profit for each book sold is $3.50

What is the median of this data set?
The median of a data set with an even number of values is calculated by taking the average of the two middle values. For a data set with an odd number of values, the median is simply the middle value.
Explanation:The median of a data set with an even number of values is calculated by taking the average of the two middle values. For example, if the data set is 6.8, 7.2, the median would be (6.8 + 7.2) / 2 = 7.
However, if the data set has an odd number of values, the median would simply be the middle value. For example, if the data set is 3, 5, 8, the median is 5.
It's important to note that the median is used to find the middle value of a data set and is often preferred over the mean when there are outliers in the data.

Suppose that in a certain triangle, the degree measures of the exterior angles are in the ratio 2:3:4. If the largest interior angle measures y degrees, what is the value of y?
Final answer:
To find the largest interior angle y in a triangle with exterior angles in the ratio 2:3:4, we use the fact that the sum of a triangle's exterior angles is 360° to find the value of each exterior angle, then deduce y as the supplement of the largest exterior angle, resulting in y being 20°.
Explanation:
To find the value of the largest interior angle y in a triangle where the exterior angles are in the ratio 2:3:4, we start by understanding that the sum of the exterior angles of any triangle is 360°.
This means that the exterior angles in this triangle are 2x, 3x, and 4x degrees, respectively, where x is a common multiple.
Given that the sum of these angles must be 360°, we can write the equation 2x + 3x + 4x = 360°, simplifying to 9x = 360° and solving for x gives us x = 40°.
The largest exterior angle is 4x, which equals 160°. Since the exterior angle is supplementary to the interior angle it shares a vertex with, the largest interior angle y is therefore 180° - 160° = 20°.
Thus, the value of y is 20°.

Each trip, a bus drops off more fans at a concert. On the first trip, the bus dropped off 30. On the 14th trip, which was the last one, the bus dropped off 95 fans. How many fans did the bus deliver to the concert in total
Answer: There are 875 fans the bus deliver to the concert in total.
Step-by-step explanation:
Since we have given that
On the first trip, the bus dropped off = 30
Here a = first term = 30
On the 14 trip, the last trip, the bus dropped off = 95
i.e. [tex]a_{14}=95[/tex]
So, the total number of fans the bus deliver to the concert is given by
[tex]S_{14}=\frac{n}{2}(a+a_n)\\\\S_{14}=\frac{14}{2}(30+95)\\\\S_{14}=7(30+95)\\\\S_{14}=125\times 7\\\\S_{14}=875[/tex]
Hence, there are 875 fans the bus deliver to the concert in total.

Carla sells hot coffee, cider and tea from a sidewalk cart near wall street in new york city. last month she sold $4,500 worth of product to 1,000 customers. she spent $800 on buying her beverages in bulk. her monthly costs are: utilities = $100, salary = $2,000, advertising = $0, insurance = $0, interest = $0, rent (cart) = $600, depreciation = $0. calculate carla's average sale per customer.
The average sale per customer for Carla is $4.50.
To find Carla's average sale per customer, we need to determine the total revenue and the total number of customers.
The average sale per customer is calculated by dividing the total revenue by the total number of customers.
Given:
- Total revenue for the month: $4,500
- Total number of customers for the month: 1,000
The average sale per customer is calculated as:
[tex]\[ \text{Average sale per customer} = \frac{{\text{Total revenue}}}{{\text{Total number of customers}}}. \][/tex]
Plugging in the given values:
[tex]\[ \text{Average sale per customer} = \frac{{4,500}}{{1,000}} = 4.5. \][/tex]
Thus, the average sale per customer for Carla is $4.50.

Sue’s Corner Market has a markup of 60% on bottled water. If the market sells a bottle of water for $2, find the original amount that Sue pays.
Markup is the amount added to the cost price of goods to cover overhead and profit.
Sue’s Corner Market has a markup of 60% on bottled water.
Let us say original price was $x.
Now price after markup is $2.
So we can make an equation like:
original price + markup price = price after markup
x + 60% of x =2
[tex] x + 0.6x =2 [/tex]
[tex] 1.6x =2 [/tex]
dividing both sides by 1.6
x= 1.25
So original price was 1.25 dollars.

A. 8.0 cm
B.16.5 cm
C. 24.7 cm
D. 272.0 cm
The other leg of the right triangle will be 16.5cm.
Legs of a right triangle:The side which shares the common/neighboring border to the right angle in a triangle is called legs.
Pythagoras theorem:It states that the sum of the areas of the two squares on the legs equals the area of the of the square on the hypotenuse.
According to the given question, we have
length of one leg of the right triangle is 13cm.
hypotenuse of the right triangle is 21 cm .
Let x be the length of the other leg.
Now, according to the Pythagoras theorem
We can write as
[tex](21)^{2} = x^{2} +(13)^{2}[/tex]
⇒ 441 = [tex]x^{2} +169[/tex]
⇒[tex]441-169 =x^{2}[/tex]
⇒ [tex]272 =x^{2}[/tex]
⇒ [tex]x = \sqrt{272}[/tex]
⇒[tex]x = 16.49[/tex] ≈ 16.5cm
Hence, the other leg of the right triangle will be 16.5cm.
