Two car-rental agencies are competing for business. mertz charges $35 a day and $0.15 per mile, and mavis charges $20 a day and $0.45 per mile. a. write an equation that represents the charges to rent a car at each agency.

Well we overall have two different equations we can make here with two different variables. If 35 & 20 were to be our daily charge, and y is our per mile charge, we can infer that x times y is equal to our overall car-rental price, so if we set it out correctly, our equations should be
35 x (y).15 =
20 x (y).45 =
