Question

The table shows the number of laps jogged by Cameron last weekend. Day Number of Laps Saturday 21 Sunday 16.5 What was the percent of decrease in the number of laps jogged from Saturday to Sunday? Round the percent to the nearest tenth if necessary.

Answer 1

Answer: To find the percent of the decrease in the number of laps jogged from Saturday to Sunday, we can use the following formula:

percent decrease = (change in value / original value) x 100

In this case, the original value is the number of laps jogged on Saturday, which is 21 laps. The change in value is the difference in the number of laps jogged from Saturday to Sunday, which is 21 - 16.5 = 4.5 laps.

So, substituting these values into the formula:

percent decrease = (4.5 / 21) x 100

percent decrease = 0.214 x 100

percent decrease = 21.4%

Rounded to the nearest tenth, the percent of decrease in the number of laps jogged from Saturday to Sunday is 21.4%.
