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?

d. Marcus rents a car for 5 days.

Step-by-step 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.

answer: the equation matches the regression

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
