Question

A music video website received 5,000 comments on a new song they released. The next day, the artist performed the song on television and an additional 1,500 comments were made on the website. What was the percent of increase?

Answer 1

$$\begin{matrix} 5000\ comments && 100\% \\ 150 0\ comments& & x\% \end{matrix}$$

$$x=\dfrac{1500\ comments}{5000\ comments}\cdot100\%=30\%$$

The increase is 30%.
