Answer 1

ANSWER:

The attendance before the increase is 4714

STEP-BY-STEP EXPLANATION:

From the statement we can propose the following equation

$\begin{gathered} x\cdot(1+0.17)=5515 \\ \text{where x is attendance before the increase} \end{gathered}$

solving for x:

$\begin{gathered} x\cdot(1.17)=5515 \\ x=\frac{5515}{1.17} \\ x=4713.68\cong4714 \end{gathered}$
