Question

Marcus is considering two car rental plans. Plan A can be modeled with the equation C = 30 d , and Plan B can be modeled with the equation C = 25 d + 15 , where C represents the cost in dollars and d represents the number of days a car is rented. Which statement would justify selecting Plan B instead of Plan A?

Answer 1

Answer: Marcus rents a car for 3 days.

Answer 2

Answer: d. Marcus rents a car for 5 days.

Explanation:

If D = the number of days then C=25(5)+15=140(plan b)

C=30(5)=150 (plan a)

Plan b is better because plan b cost less than plan a for 5 days.
