Which statement best explains who earns the most money per item sold
Since you didn’t include the statements, the answer is Marsha.
Why? Her slope increases more per item sold than Dreya.
[tex]\text{The slope formula is: }y=mx+b[/tex]
Marsha earns the most money per item sold because her profit margin is higher, and her earnings increase more rapidly as she sells more items compared to Dreya. Correct option is 2.
Marsha earns the most money per item sold because her profit margin per unit is higher than Dreya's. Profit margin is calculated by subtracting the cost of producing or acquiring an item from its selling price and then dividing the result by the selling price. If Marsha's profit margin per item is larger than Dreya's, it means that she earns more money for each item sold.
The statement also mentions that Marsha's slope increases more per item sold than Dreya's. This likely refers to a graphical representation where Marsha's revenue or profit line has a steeper slope than Dreya's. A steeper slope indicates that Marsha's earnings increase at a faster rate for each additional item sold, reinforcing the idea that she earns more money per item.

A restaurant has 1,996 forks, 1,745 knives and 2,116 spoons. The owner wants to have 2,000 of each utensil. She can buy more utensils or donate extra utensils. How many additional forks and knives are need? How many extra spoons are there?
Answer:
4 forks and 255 knives will be needed more, while 116 spoons are extra.
Step-by-step explanation:
A restaurant has 1996 forks, 1745 knives and 2116 spoons.
Owner wants to have 2000 of each utensil.
So make them equal to 2000, number of forks needed = 2000 - 1996 = 4
[Subtracted from 2000 because number of forks are less than 2000]
Number of knives needed = 2000 - 1745
= 255
[Again subtracted from 2000 because number of knives are less]
Number of spoons to be donated = 2116 - 2000
= 116
[2000 is subtracted from total number of spoons because spoons are more than 2000]
Therefore, 4 forks and 255 knives will be needed more, while 116 spoons are extra.

A coffee merchant wants to make 6 pounds of a blend of coffee costing five dollars per pound. The blend is made using a six dollar per pound grade coffee and a three dollar per pound grade of coffee. How many pounds of each of these grades should be used?
Answer:
We should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.
Step-by-step explanation:
The blend should,
Cost = $5
Weigh = 6 pounds.
Lets take the weight of $6 coffee as [tex]x[/tex] pounds
And lets take the weight of $3 coffee as [tex]y[/tex] pounds.
Lets write an equation for the weight of the blend,
[tex]x+y=6[/tex] <---------- 1st equation.
[tex]\frac{6x+3y}{x+y} =5[/tex]
=[tex]6x+3y=5x+5y[/tex]
=[tex]x=2y[/tex] <---------- 2nd equation
We can substitute to x in 1st equation from 2nd equation,
⇒[tex]2y+y=6[/tex]
=[tex]2y+y=6[/tex]
=[tex]3y=6[/tex]
=[tex]y=2[/tex]
We can substitute y value to 2nd equation to find x,
⇒[tex]x=2y[/tex]
=[tex]x=2*2[/tex]=[tex]x=4[/tex]
Therefore, we should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.
25% of the customers at Terrific Tresses hair salon have curly hair. If the salon has 644 customers, How many do not have curly hair?
To find the number of customers without curly hair at the salon, we multiply the total number of customers by the percentage with curly hair and subtract that from the total number of customers.
Explanation:To find the number of customers who do not have curly hair, we first need to determine the number of customers who do have curly hair. We know that 25% of the customers have curly hair, which is equal to 0.25. To find this number, we multiply 0.25 by the total number of customers. So, 0.25 * 644 = 161.
Since we have the number of customers with curly hair, we can subtract this from the total number of customers to find the number without curly hair. So, 644 - 161 = 483 customers do not have curly hair at Terrific Tresses hair salon.

x, equals
Answer:
x = -[tex]\frac{17n+r}{n-34}[/tex]
Step-by-step explanation:
We have to solve the equation for the value of x.
n(17 + x) = 34x - r
17n + nx = 34x - r [By Distributive property ]
17n + nx - 17n = 34x - r - 17n [subtracting 17n from both the sides of the equation]
nx = 34x - r - 17n
nx - 34x = 34x - r - 17n - 34x [Subtracting 34x from both the sides of the equation]
x(n - 34) = -(r + 17n) [Division by (n - 34) on both the sides of the equation]
x = -[tex](\frac{17n+r}{n-34})[/tex]
This is the solution for x in terms of constants n and r is x = 17n + r/34 - n
Solving for x in the equation n(17 + x) = 34x − r
To solve for x, we begin by isolating x on one side of the equation. Given the equation:
n(17 + x) = 34x - r
First, distribute n on the left-hand side:
17n + nx = 34x - r
Next, rearrange the equation to place all terms involving x on one side:
17n + r = 34x - nx
Factor out x on the right side:
17n + r = x(34 - n)
Solve for x by dividing both sides by (34 - n):
x = 17n + r/34 - n
This is the solution for x in terms of constants n and r.

Whitney sells cars at a local dealership. She receives a monthly salary of $1,337.00 and a $177.00 commission on each car she sells. If Whitney receives her commission check at the end of the month along with her salary check, which of the following equations can be used to determine her total pay for the month? (Let x represent the number of policies sold and y represent the total amount of pay for the month.)
Answer: y = 1,337.00 + 177.00x
Explanation:
The total pay for the month that Whitney receives is a composition of the fixed salary, $1,337.00, and the commission, $177.00 one ach car she sells.
The commision, in turn is a function of the number of cars that she sells. So the composed function is the sum of two terms: the basic salary and the comissions.
The variables used are:
dependent variable, total pay for the month: yindependent variable, number of policies sold: xHence, the function is: y = 1,337.00 + 177.00x
For what value of n does (1/36)^n=216
(1/36)^n = 216
Rewrite 36 as 6^2
(1/6^2) ^n = 216
Since 36 is in the denominator, the exponent is negative
(6^-2) ^n = 216
Rewrite 216 as 6^3
(6^-2)^n = 6^3
We know that a^b^c = a^(b*c) so
6^(-2n) = 6^3
Since the bases are the same, the exponents are the same
-2n = 3
Solving for n
n =-3/2
n = -1.5
Final answer:
The value of n for which [tex](1/36)^n[/tex] equals 216 is -3/2. This is found by expressing both sides of the equation with the common base of 6 and equating the exponents, then solving for n.
Explanation:
To find the value of n for which [tex](1/36)^n[/tex]= 216, first we express 216 as a power of 6, since 36 is a power of 6 (36 = [tex]6^2[/tex]): 216 = [tex]6^3[/tex]. We can then rewrite the equation using this equivalent expression of 216 and the knowledge that 1/36 is [tex]6^-2[/tex]:
[tex](6^-2)^n = 6^3[/tex]
Using the power of a power rule, this simplifies to:
[tex]6^(-2n) = 6^3[/tex]
Since the bases are the same, the exponents must be equal:
-2n = 3
Dividing both sides by -2 to solve for n, we get:
n = -3/2

The sun produces 3.8*10^27 joules of energy per second . How much energy is produced in a year. The year is approximately 31,000,000 seconds
Open that attachment and that should be the answer.
Answer:
1.178 x 10^35 Joule
Step-by-step explanation:
Energy produced by sun in one second = 3.8 x 10^27 J
Energy produced by sun in a year = Energy produced by sun in one second x number of seconds in one year
According to the question, the number of seconds in one year
= 31,000,000 seconds
Energy produced by the sun in one year = 3.8 x 10^27 x 31,000,000
= 1.178 x 10^35 Joule
Thus, the energy produced by the sun in a year is 1.178 x 10^35 Joule.
