Question

To reduce wear and tear on the family vehicle, you decide to rent a car. Happy Harry’s Rentals has a $500 fee for any rental up to eight days. Smilin’ Sam’s offers the same car for $200 plus $50 per day. Which deal is better?

Answer 1

Let's use 8 days as the maximum time we are going to be renting the car.

Putting that into the equation means, 500$ for Harry's Rentals and Smilin' Sam's at $600.

Therefore, Happy Harry's Rentals are better for the 7th and 8th days while Smiling Sam's are the better from day's 1 to 6.

Work:

500$ is a fixed value so it doesn't change (constant)

200 + 50x

x = days

8 days = 8x

200 + 50(8)

200 + 400 = 600
