Question

A) 11.8%
B) 12.5%
C) 12.8%
D) 13.2%

Answer 1

To calculate the percent of increase between the first and second week, find the difference in times and divide it by the first time.

Step-by-step explanation:

To calculate the percent of increase, we need to find the difference between the two times it took to mow the yard and then divide that difference by the first time. Let's calculate it:

First week: 136 minutes

Second week: 153 minutes

Difference: 153 - 136 = 17

Percent of increase: (17/136) * 100 = 12.5%

Therefore, the correct answer is B) 12.5%.
