Suppose that a car rental agency charges a fixed amount per day plus an amount per mile for renting a car. Heidi rented a car one day and paid $100.00 for 300 miles. On another day she rented a car from the same agency and paid $150.00 for 550 miles. Determine the linear function that the agency could use to determine its daily rental charges.
