7-22.

Alan was paying a dinner check, but he was not sure how much he should tip for his bill of $\27.38$. If a $15\%$ tip is standard, about how much should Alan leave for the server?

To find a percent of a number, you should first change the percent to a decimal. What is the decimal for $15\%$?

Next, multiply the decimal value $0.15$ by the amount $27.38$. This will give you $15\%$% of $\27.38$.

$15\%$ of $\27.38$ is approximately $\4.11$.
