Christian got a haircut yesterday afternoon. If the hair stylist charged $18 and Christian gave a 20% tip, how much did he pay for the haircut?
A.
$3.60
B.
$14.40
C.
$21.60
D.
$22.60
The cost of the haircut is $18, and Christian gave a 20% tip. To calculate the tip amount, we will multiply $18 by 20% (0.20).
Tip = $18 * 0.20 = $3.60
To find the total amount Christian paid for the haircut, we add the cost of the haircut and the tip amount.
Total amount paid = $18 + $3.60 = $21.60
Therefore, the correct answer is C. $21.60.
