Question

Maximilian wants to rent a car for 10 days, and he has two options. The first rental car company charges a $35 rental fee and an amount of $110 for 3 days. The second rental car company's offer can be modeled by the equation y=28x+15, where x is the number of days and y is the total cost of renting a car.

Which rental car company (first or second) is the better option and why?

Answer 1

The second rental car company is better because it is cheaper

Explanation:

First option :

The first rental car company charges a $35 rental fee

An amount of $110 for 3 days.

So, Total cost for 3 days = 35+110=145

Second option:

The second rental car company's offer can be modeled by the equation :

`y=28x+15`

Where x = number of days

y = total cost of renting a car

Substitute x = 3

y=28(3)+15

y=99

So, Total cost for 3 days = $99

So, Option 2 is cheaper

So, The second rental car company is better because it is cheaper
