2. A car rental agency charges $75 per day, which includes 100 miles. For each mile over 100 miles, there is an additional cost of $0.35 per mile. Write and solve an equation relating m, the number of miles driven, if the total cost for a one-day rental was $131.

• 75+0.35=131; m=260

• 0.35(m-100)=131; m=100

• 75+(m-100)=131; m=100

• 75+0.35(m-100)=131; m=260
