A. System:
y = 0.05x + 28
y = 0.07x + 25
B. Substitute:
0.07x + 25 = 0.05x + 28
C. At what number of miles will the cost the same?
150
Step-by-step explanation:
Let y = cost. Let x = number of miles.
Five Star CArz:
y = 0.05x + 28
GoCars:
y = 0.07x + 25
System of equations:
y = 0.05x + 28
y = 0.07x + 25
Substitute y of the first equation with 0.07x + 25
0.07x + 25 = 0.05x + 28
0.02x = 3
x = 150
The costs are the same at 150 miles.
The answer will be 52 hope this helps you
