Mabel is comparing the prices of two car rental companies. Company A charges $35 per day and an additional $15 as service charge
s. Company B charges $42 per day and an additional $10 as service charges. Part A: Write an equation to represent each company's total charges for renting a car for a certain number of days. For both equations (one for Company A and one for Company B), define the variable used. (4 points)
Part B: Which company would charge less for renting a car for 6 days? Justify your answer. (3 points)
Part C: How much money is saved by using the services of Company A instead of Company B to rent a car for 10 days? (3 points)
Company A : C = 35D + 15....C is total cost and D is number of days company B : C = 42D + 10...C is total cost and D is number of days ================ which company charges less for renting for 6 days company A : C = 35(6) + 15 = 225
company B : C = 42(6) + 10 = 262
so company A charges less when renting for 6 days ================= for 10 days... company A : C = 35(10) + 15 = 365
company B : C = 42(10) + 10 = 430
so there would be (430 - 365) = 65 saved when using company A instead of company B
