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
The answer to the question
Ratio is 6:5
6+5=11
Men: 6 parts of 11 = 3600
6=3600
1=x
X=3600/6
=600.
Women: 5 parts of 11
1 part = 600
5 parts = 600x5
=3000
