Exercise 13 Page 134

To solve problems that involve percent, use the percent equation.

Equation: 230 = n* 200
Solution: n = 115 %

Practice makes perfect

Let's start by recalling that we can use the percent equation to solve problems that involve percent. Percent Equation [0.3em] part = percent * whole We want to find what percent of 200 is 230. Let n represent the percent. 230 = n * 200 Now we will solve the equation that we got for n. To do so, we will use the Division Property of Equality.

230=n* 200
230/200=200n/200
230/200=200n/200
230/200=n
1.15 =n
n = 1.15

We found that n= 1.15 is a solution to the equation. To write the decimal as a percent, we need to move the decimal point two places to the right and write the percent symbol. 1.15 = 115 % We got that 230 is 115 % of 200.
