Question

Enrollment in a summer program offered by the Parks and Recreation Department increased from 87 in 2018 to 126 in 2019. What was the percent increase in enrollment? Round to the nearest whole number.

Answer 1

To calculate the percentage increase, we shall observe the following steps

Step 1: get the initial and final values for the enrollment

Initial value = 87

Final value = 126

Step 2: Use the formula below

`\text{percentage increase =}\frac{f\text{ inal -initial}}{i\text{ nitial}}\text{ x 100\%}`

Step 3: Substitute the value

`\begin{gathered} \frac{126\text{ - 87}}{87}\text{ X 100\%} \\ \\ \Rightarrow\text{ }(39)/(87)\text{ x 100 \%} \\ \Rightarrow0.4483\text{ x 100\%} \\ \Rightarrow44.83\text{ \%} \end{gathered}`

To round up the answer to the nearest whole number = 45%

The percentage increase is 45%
