Question

The percent of working students increased by 14.1% to 31.7%, what was the percent prior to the increase? (Express your answer rounded correctly to the nearest tenth of a percent!)

Answer 1

124.8 %

Explanation:

Given,

Initial percentage of working students = 14.1%,

Final percentage of working students = 31.7%,

Thus, the percentage increase =
`\frac{\text{Final percentage-initial percentage}}{\text{Initial percentage}}* 100`

`=(31.7 - 14.1)/(14.1)* 100`

`=(17.6)/(14.1)* 100`

`=(1760)/(14.1)`

≈ 124.8 %
