sorry lol

aveline · Answer

Ok. Let's use the equation: 110+0.20m=70+70m
The 'm' represents the numbers of miles driven
Let's simplify the equation:
110+0.20m=70+0.70m
40+0.20m=0.70m
40=0.50m
80=m

So after 80 miles, the costs will be about the same. Therefore, after 81 miles...

erniellyd28 · Answer

so 81 is the answer?

aveline · Answer

81 miles is the answer. It would cost $126.20 to rent from company A after 81 miles. It would cost $126.70 from company B.
