Answer:
D) 150 miles.
Explanation:
The computation is shown below:
Given that
The Cost of the car rental agency of A is $50 + 0.10 per mile
The Cost of the car rental agency of B is $20 + 0.30 per mile
Here we assume the per mile be x
Now we equate these equations
SO,
$50 + 0.10x = $20 + 0.30x
$30 = 0.20x
x = 150
SO it would be more than 150 miles
