A set of pencils sells for $2.25 and cost $0.60 to make. Twenty percent of the profit goes to a school.

Question

If 450 sets are sold, what is the amount of money that will go to the school.?

I need the answer.. And how to do it.

Answer 1

Profit is Sales - Cost.

Sale price is $2.25 and cost is $0.60, therefore profit is $1.65 per set of pencils.

There's two ways you can go from here:

1) $1.65 x 450 = 742.50 is the total profit. Then multiply by 20% to find the amount given back. 742.50x .20= 148.50

2) you can find the amount per unit then multiply by total units. 1.65 x .20 =.33 then .33x 450= 148.50

Answer 2

You know EACH set costs 2.25. Meaning ONE set costs 2.25. Therefore if there are 450 sets,

450 x 2.25 = total cost.

Twenty percent of the total cost goes to the school.

Total cost = 1012.5

Twenty percent of 1012.5 is

0.20 x 1012.5 = 202.5

ANSWER: $202.50
