Ответ:
125 miles
Step-by-step explanation:
Write formulas for the amount of $ that would be due each of the two companies and set these equal to one another prior to solving for the number of days:
A: $35 + ($0.45/mile)x
B: $60 + ($0.25/mile)x
Then $35 + ($0.45/mile)x = $60 + ($0.25/mile)x, or
($0.20/mile)x = $25
$25
dividing both sides by $0.20 yields x = = 125 miles
$0.20/mile
The charges made by the two companies would become equal after the 125th mile. After that, Company B would become cheaper.
