Chang rented a truck for one day. there was a base fee of $17.95 , and there was an additional charge of 85 cents for each mile driven. chang had to pay $211.75 when he returned the truck. for how many miles did he drive the truck?

Chang drove the truck 228 miles.
To figure this question out, you have to write an equation. Your equation would be 17.95 (for the base fee) plus .85x (85 cents for each mile) equals 211.75 (total cost). Equation---> 17.95+.85x=211.75
To solve this equation, first, you have to subtract 17.95 from both sides. After you do this, you end up with .85x=193.8
The next thing you have to do to solve this equation is divide both sides by .85
Once you do this you should end up with x=228. This would be your answer.
