Question

a builder could get three sheets of sheetrock for $2 if he bought 15 sheets how much money would he have spent

Answer 1

Davis, this is the solution to the problem:

Step 1: Let's review the information given to us to answer the problem correctly:

Price of three sheets of sheetrock = $ 2

Step 2: Let's calculate the price for 15 sheets, using the Direct Rule of Three, as follows:

Sheets Price

3 2

15 x

_______________________

3 * x = 15 * 2

3x = 30

Dividing by 3 at both sides:

3x/3 = 30/3

x = 10

15 sheets will cost $ 10
