Samantha hires a car service to travel from her office to a client's location. The service charges a flat fee of $4.50 to book the ride, plus $3.00 for every mile traveled. If Samantha's trip costs her a total of $31.50, write an equation that represents this situation. Let m represent the number of miles to the client's location.

• 4.50 + 3 = 31.50

• m + 4.50 = 31.50

• 4.50 + 3m = 31.50

• 4.50m + 3 = 31.50
