Chau rented a truck for one day. There was a base fee of $19.95, and there was an additional charge of 99 cents for each mile driven. Chau had to pay $157.56 when he returned the truck. For how many miles did he drive the truck?

139 miles

Step-by-step explanation:

1) find the equation:

157.56=19.95+0.99x

we are solving for x

2) subtract 19.95 from both sides:

157.56=19.95+0.99x

-19.95     -19.95

137.61=0.99x

3) we divide 0.99 from both sides:

137.61=0.99x

/0.99      /0.99

139=x

Chau drove 139 in the truck in total.
