Question

Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost?

A. Find the answer.

B. Write a formula for the problem.

Answer 1

22.20$

3/5 * cost = 13.32

Explanation:

3/5 * cost (total price) = 13.32 (we know that 3/5 of the price is 13.32)

to solve

5/3 to cancel out 3/5 and isolate the cost

5/3 * 13.32 = 22.20

Answer 2

a. $22.2

b= 13.32/x=3/5

Explanation:

13.32/x=3/5

13.32×5=66.6

66.6/3=22.2

x(present cost)=$22.2
