Chapter 6 - Percent - 6.5 Using the Percent Equation - 6.5 Exercises - Page 428: 34


Correct answer: $x=0.005*1300=\$6.50$

Work Step by Step

First, we solve the problem the correct way. To find $\frac{1}{2}\%$ of $\$1300$, we set up a proportion: $\frac{0.5}{100}=\frac{x}{1300}$ $x=0.005*1300=\$6.50$ The other classmates used a wrong decimal value for the percent: $x=0.0005*1300=\$0.65$ (WRONG) $x=0.05*1300=\$65$ (WRONG) $x=0.5*1300=\$650$ (WRONG) Thus it's important to convert percents to decimals properly.
