120 + 0.40m = 50 + 0.50m
120 - 50 = 0.50m - 0.40m
70 = 0.10m
70/0.10 = m
700 = m....they will be the same at 700 miles

The number of miles in a day where the rental cost for company a and for company b should be the same is 700 miles.

Given that,

  • For company a, the truck was rented for $120 & $0.40 per mile.
  • For company b, the truck was rented for $50 & $0.50 per mile.
  • Let us assume the number of miles be x.

Now the following equation should be made

$120 + $0.40x = $50 + $0.50

$120 - $50 = $0.50 - $0.40x

$70 = $0.10x

x = 700 miles

Therefore we can conclude that the number of miles in a day where the rental cost for company a and for company b should be the same is 700 miles.
