Question

what is the percent of increase from 7 to 9.4? round your answer to the nearest tenth of a percent and include a percent sign (%)

Explanation:

Step1: Calculate the difference

$9.4 - 7= 2.4$

Step2: Use percent - increase formula

Percent increase=$\frac{\text{increase}}{\text{original number}}\times100\%=\frac{2.4}{7}\times100\%$

Step3: Calculate the result

$\frac{2.4}{7}\times100\%\approx0.342857\times100\% = 34.3\%$ (rounded to the nearest tenth of a percent)

Answer:

$34.3\%$
