.
A=Total cost for $30 a day service
B=Total cost for $40 a day service
m=mileage
.
A=$30+$0.25m
B=$40+$0.20m
Cost is the same when A+B:
A=B
$30+$0.25m=$40+$0.20m Subtract ($30+$0.20m) from each side.
$0.05m=$10 Divide each side by $0.05
m=200
ANSWER: The two services cost the same when the mileage is 200 miles.
