Question

Last week, you finished Level 2 of a video game in 32 minutes. Today, you finished Level 2 in 28 minutes. What is your percent of change?

Answer 1

The first step to solve this problem is to compute how much change in minutes were you able to have today compared to the last week.

32 minutes – 28 minutes = 4 minutes faster than last week

To compute the percent of change you have to divide the change in minutes to the duration in minutes for the last week:

4 minutes / 32 minutes = 0.125 or 12.5% faster than last week
