Question

what is the percent of increase from 39.2 to 68.2? round your answer to the nearest tenth of a percent and include a percent sign (%)

Explanation:

Step1: Identify the formula for percent - increase

Percent increase=$\frac{\text{New value}-\text{Original value}}{\text{Original value}}\times100\%$

Step2: Substitute the given values

The original value is $39.2$ and the new value is $68.2$. So, $\frac{68.2 - 39.2}{39.2}\times100\%=\frac{29}{39.2}\times100\%$.

Step3: Calculate the fraction value

$\frac{29}{39.2}\approx0.74$. Then $0.74\times100\% = 74.0\%$.

Answer:

$74.0\%$
