Question

The population of the 7th and 8th grade was 720 students in 2016. In 2017, it was 809. What is the percent increase in population to the nearest tenth?

A. 10.2% C. 11%
B. 12.4% D. 12.6%

Answer 1

Option B. 12.4% is the correct answer

Step-by-step explanation:

The percent increase is given by:

$Percent\ Increase = \frac{Increase}{old\ value}*100$

Where

$Increase= New\ Value-Old\ Value$

Given

Old Value = 720

New value = 809

$Increase = 809-720\\=89\\So,\\Percent\ increase =\frac{89}{720}*100\\=12.36\%$

Rounding off to the nearest tenth

12.4%

Hence,

Option B. 12.4% is the correct answer
