Answer:
The rental rate for the Fords is of $12 per day.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x is the cost of a Nissan.
y is the cost of a Ford.
z is the cost of a Chevrolet.
Three Nissans, two Fords, and four Chevrolets can be rented for $106 per day.
This means that:
Two Nissans, four Fords, and three Chevrolets cost $107 per day
This means that:
Four Nissans, three Fords, and two Chevrolets cost $102 per day.
This means that:
From the first equation:
Replacing into the third equation:
From the second equation:
Find the rental rate for the Fords.
We have to find y, so:
The rental rate for the Fords is of $12 per day.
