For 60 miles per day, the cost will be same.
Step-by-step explanation:
Company A;
Per day charge = $13.00
Per mile charge = $0.28
Let,
m represent the number of miles per day.
A(x) = 0.28x+13.00
Company B;
Per day charge = $25.00
Per mile charge = $0.08
B(x) = 0.08x+25.00
For same number of miles;
A(x) = B(x)
[tex]0.28x+13.00=0.08x+25.00\\0.28x-0.08x=25.00-13.00\\0.20x=12.00\\[/tex]
Dividing both sides by 0.20
[tex]\fac{0.20x}{0.20}=\frac{12.00}{0.20}\\x=60[/tex]
For 60 miles per day, the cost will be same.
