Exercise 1 Page 132

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

Equation: p = 0.88* 300
Solution: p = 264

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 In this case, we are asked to find 88 % of 300, which means that we want to find the part. Let p represent the part. p = 88 % * 300 Before we can solve the equation that we got, 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.
percent as decimal: 0.88
We got that 88 % is equal to 0.88. p = 88 % * 300 [0.3em] ↓ [0.3em] p = 0.88 * 300 Finally, let's solve the equation for p.
p = 0.88 * 300
p = 264
We found that p= 264 is a solution to the equation. This means that 88 % of 300 is equal to 264.
