Respuesta :
Boris drove the truck 129 miles. You take how much the base fee (16.95) and subtract it from the total of how much he had to pay (131.79). The problem would look like $131.79 - $16.95 = $114.84. Then would would take 114.84 and divide it by the cost of one mile. This problem would look like $114.84 divided by $0.89 = 129. This means the driver drove 129 miles! I hope this helps!
