Question

The cost of renting a car is given by the formula C = 50n + 0.15d, where C is the in dollars, n is the number of days' rental, and d is the distance driven in miles. How much would it cost to rent a car for a 15-day trip, and drive 475 miles each day? (show all work please)

Answer 1

Step-by-step explanation:

so, again, the function definition is

C = 50n + 0.15d

15 days means n = 15.

475 miles driven each day ? that is

475 × 15 = 7,125 miles driven in total.

so, d = 7,125

therefore,

C = 50×15 + 0.15×7125 = 750 + 1,068.75 = $1,818.75

that is how much this trip would cost.
