Question

santino is renting a canoe from a local shop that charges a $10 fee, plus an hourly rate of $7.50. For how long can santino rent a canoe if he pays a total of $70

Answer 1

Santino rented the canoe for 8 hours.

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.
