Answer: The charge was right.

Step-by-step explanation:

If he charged $18 per hour, it means he charged $18 for 60 minutes. He worked for 2 hours 15 minutes which is (60 * 2) + 15 = 135 minutes. For 135 mins, (135 * 18) : 60 = 40.5.

He drove 21 miles to his house and 21 miles back. That is 21*2 = 42. And for $0.27 = $11.34.

Adding the costs, 40.5 + 11.34 = $51.84
