Triangle Truck Rental chanrges $30 per day and 40 cents a mile.
C= 30+0.4m
where m is the number of miles & c is the total cost
Circle Rent A Truck $55 a day and 30 cents a mile.
c= 55+0.3m
If c= same then
30+0.4m = 55+0.3m
0.4m-0.3m = 55-30
0.1m = 25
m = 250 miles.
for 250 miles the cost will be the same
