Answer:
The cost of renting will be the same for 100 miles.
Step-by-step explanation:
Let n the number of miles and C be the cost. We can represent the cost equations for each companies:
A: C = 45 + 0.1n
B: C = 40 + 0.15n
They want to know when the cost will be the same, so we can set the above 2 equations equal to each other and solve for n:
45 + 0.1n = 40 + 0.15n
0.05n = 5
n = 100
