A car rental agency charges $60 per day, which includes 120 miles. For each mile over 120 miles, there is an additional cost of $0.70 per mile.
Which equation shows m, the number of miles driven, if the total one-day rental costs $242?
60+0.70m=242
60+0.70(m+120)=242
60+0.70(m−120)=242
60+120+0.70m=242
