Chang rented a truck for one day. There was a base fee of 15.95, and there was an additional charge of 88 cents for each mile driven. Chang had to pay 210.43 when he returned the truck. For how many miles did he drive the truck?

221 Miles

Step-by-step explanation:

Since there is a base fee, you substract that from the total.

210.43 - 15.95 = 194.48.

And since it was .88 per mile, you just divide 194.48 by .88 to get 221

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
