Mike rented a truck for one day. There was a base fee of $17.99, and there was an additional charge of 83 cents for each Mike driven. Mike had to pay $140 when he returned the truck. For how many miles did he drive the truck?

Respuesta :

17.99 + 0.83m = 140
0.83m = 140 - 17.99
0.83m = 122.01
m = 122.01 / 0.83
m = 147 <== Mike drove 147 miles
