Answer:

21.6 is the payment amount from mom to Emily

Step-by-step explanation:

Proportion

Payment / unit distance = total payment/total distance

Givens

Payment =0.90
Unit distance = 0.75 miles
Total payment = x
Total distance = 18 miles

Solution

0.9/0.75 = x / 18 Multiply both sides by 18

0.9 * 18/0.75 = x * 18/18 Simplify.

16.2 / 0.75 = x Simply the left

21.60 = x
