Question

To raise money, a school is selling containers

of frozen cookie dough for $4.25 each. The

school pays $2.50 for each container.

a) Write two different algebraic

expressions that represent the profit

from the sale of any number of

containers of cookie dough.

b) Evaluate each expression for total sales

of 174 containers.

Answer 1

Selling containers of frozen cookie dough for $4.25 each means that you multiply or times four dollars and twenty five cents by a variable. Lets use x and set it equal to y.

4.25x = y.

This allows you to find the revenue or money earned from cookie dough sales.

Becsuse x=174 we must plug this into the equation that we made.

4.25(174)=y which equals 739.5 dollars.

To evaluate this the given unit with the second part of the question we must write another equation.

Since we know that the school pays $2.50 for each container we must plug this into our equation:

Remember:

To check your units for the final answer.

Check the number of units being used-x equals 174.

Y=2.50x->2.50(174)= $435 because our units are dollar-based.

Final Answers:

The school would pay a total or sum of $435 because that is the amount to buy 174 units at a cost of $2.50.

Becsude the school sales each unit or container of cookie dough for $4.25, they would earn a total of $739.5.

Y=$4.25(174)

= $739.5

If your answer needs to be rounded by the nearest dollar it would be $740.
