Question

Regina ran 31 miles last week. This week, she ran 42.5 miles. What is her percent increase to the nearest tenth?

Answer 1

37.1%

Explanation:

You want the percent increase from 31 to 42.5.

Percent change

The percent change is calculated from ...

percent change = ((new value)/(old value) -1) × 100%

percent change = (42.5/31 -1) × 100% ≈ 37.1%

Regina ran 37.1% more miles this week.
