Answer:
Step-by-step explanation:
Company A Total Cost: Â Ca = $74
Company B Total Cost: Â Cb = $65+$0.60m, where m is the miles driven.
We want to find for what values of m with Company A charge less than Company B:
Ca < Cb  ?
$74 < $65 + $0.60m
$9 < $0.60m
15 < m
m > 15 miles
Company A will cost less than Company B when less than 15 miles are driven. Â The costs are the same for 15 miles and higher for Company B beyond 15 miles.
