Answer: $21.24
Step-by-step explanation:
This means that Jemery is paid the original cost and the tip added together. The original is 100%, so we will do the following:
100% + 18% = 118%
To answer the question, we will find 118% of $18. A percent divided by 100 becomes a decimal.
118% / 100 = 1.18
$18 * 1.18 = $21.24
He will make $21.24 for one haircut.
