miles, while Mary was charged $275.50 for 5 days and 430 miles. What does Discount Rental Cars charge per day and per mile?
1 answer:
Answer:
The charge per day is $25 and the charge per mile is $0.35
Step-by-step explanation:
Let
x -----> the charge per day
y ----> the charge per mile
we know that
3x+200y=145 -----> equation A
5x+430y=275.50 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system is the intersection point both graphs
using a graphing tool
The intersection point is (25,0.35)
see the attached figure
therefore
The charge per day is $25 and the charge per mile is $0.35

A quadratic function is a function of the form
