    Answer:

    Santino rented the canoe for 8 hours.

    Step-by-step explanation:

    The total bill is represented by the formula r(h) = $10 + ($7.50/hour)h,

    where h is the number of hours over which the canoe is rented.

    If the total bill is $70, then $70 = $10 +  ($7.50/hour)h.

    Solve this for h.  Start by subtracting $10 from both sides, obtaining:

    $60 =  ($7.50/hour)h.

    Dividing both sides by ($7.50/hour), we get:

               $60

    h = ——————— = 8 hours

          ($7.50/hour)

    Santino rented the canoe for 8 hours.
