Question

Rick weighed 158 pounds during wrestling season. Now that the season is over Rick weighs 188 pounds. How do you find the percent increase?

Answer 1

Rick had a 19.0% increase in weight rounded to the nearest tenth of a percent.

Explanation:

To find the percent change over time you use the formula:

`p = (N - O)/O * 100` where `p` is the percent change, `N` is the New Value and `O` is the Old Value. In this problem we are provided the New Value (188) and the Old Value (158). We can substitute this into the formula and calculate the percent change, `p`:

`p = (188 - 158)/158 *100`

`p = 30/158*100`

`p = 3000/158`

`p = 19.0%` rounded to the nearest tenth
