We want to find how many new comments there were on the Web site at the end of the next day. Let's use the percent equation.
part = percent * whole
We are given that a music video website received 5000 comments on a new song they released. We also know that the number of comments increased by 30 % the next day. Using the percent equation, we can find the number of comments p that were left that day.
p = 30 % * 5000
Before we can solve the equation, we need to write the percent as a decimal. We can write a percent as a decimal by ignoring the percent symbol and moving the decimal point two places to the left.
Therefore, 30 % is equal to 0.30, or 0.3.
p = 30 % * 5000 ⇓ p = 0.3 * 5000
Now let's solve the equation for p.
We got that p= 1500 is the solution to the equation. This means that the next day, 1500 additional new comments were left on the website. Finally, we can calculate how many new comments there were at the end of the next day.
5000 + 1500 = 6500
We found that there were 6500 new comments on the website at the end of the next day.
