Question

Sam rented a truck for one day. There was a base fee of $19.99, and there was an additional charge of 75 cents for each mile driven. Sam had to pay $159.49 when he returned the truck. For how many miles did he drive the truck?

Answer 1

159.49=19.99+.75x with x meaning number of miles
139.5=.75x subtract both sides by 19.99 then divide both sides by .75
x=186
Final answer: 186 miles
