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

Answer:

124.8 %

Step-by-step explanation:

Given,

Initial percentage of working students = 14.1%,

Final percentage of working students = 31.7%,

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

$=\frac{31.7 - 14.1}{14.1}\times 100$

$=\frac{17.6}{14.1}\times 100$

$=\frac{1760}{14.1}$

≈ 124.8 %
