Customer have to drive 100 miles for cost to be equal to $140
<u>Solution:</u>
Given function is as follows
C = 120 + 0.20m
Where "C" represents cost in dollar of renting a car and "m" represents number of miles.
If we see the given equation, we can say that fixed cost is 120 and variable cost is 0.20m which is dependent on number of miles car is driven.
We need to calculate number of miles so that total cost that is C = $140
On substituting C = $140 in given function, we get
140 = 120 + 0.20m
On Solving above equation for m we get
140 – 120 = 0.20m
=> 20 = 0.20m
=>
Hence customer have to drive 100 miles for cost to be equal to $140.
