Answer:
At Zippy's Rentals : y = 20 + 2 5 x
At Smyth's Rentals: y = 40 + 2 0 x
Explanation:
At Zippy's Rentals:
The per day charge = $25
The service charge = $20
So, the charges for renting cars for x days = x (Per day rental charge)
= x( $25) = 25 x
Now, total charges (y) = Service Charge + Rental fee for x days
or, y = 20 + 2 5 x
At Smyth's Rentals:
The per day charge = $20
The service charge = $40
So, the charges for renting cars for x days = x (Per day rental charge)
= x( $20) = 20 x
Now, total charges (y) = Service Charge + Rental fee for x days
or, y = 40 + 2 0 x
