Answer:
Andy's Rental Car: f(x)= 20 + (30x)
Buddy's Rental Car: f(x) 36 + (28x)
Step-by-step explanation:
First, identify what you know:
1) Andy's Rental Car charges an initial fee of $20 plus an additional $30 per day to rent a car.
2) Buddy's Rental Car charges an initial fee of $36 plus an additional $28 a day!
So, which rental car company has the better deal? Imagine you want to rent a car for ten days, which would you choose?
First, create an equation for each:
Andy's Rental Car: f(x)= 20 + (30x)
The x represents the number of days the car is rented. Multiple the days by the $30 day charge, and add it to the initial rental charge.
Buddy's Rental Car: f(x) 36 + (28x)
The x represents the number of days the car is rented. Multiple the days by the $28 day charge, and add it to the initial rental charge.
Now, input 10, for the number of days you want to rent the car for!
Andy's Rental Car: f(10)= 20 + (30 x 10)
20 + (300)
f(x) = $320
Buddy's Rental Car: f(10) = 36 + (28 x 10)
36 + (280)
f(x) = $316
So, it would be $4 cheaper to rent from Buddy's Rental Car company than Andy's Rental Car company!
Hope this helps! :)
