Question

Rafael rented a truck for one day. There was a base fee of $19.95 , and there was an additional charge of 77 cents for each mile driven. Rafael had to pay $130.83 when he returned the truck. For how many miles did he drive the truck?

Answer 1

let's convert all this dollar into cents
base fees = 1995 cents
77 cents for each mile
total he gave 13083 cents

he travel x miles

than x=( total cents - base fees ) ÷ 77

x = ( 13083 - 1995 ) ÷ 77
x = ( 11088 ) ÷ 77
x = 144 miles

so he traveled 144 miles
