A canoe rental company charges $40 to rent a canoe plus $12 an hour. How much would it cost to rent a canoe for X number of hours?

40 + 12x

To find the cost of renting a canoe for a specific number of hours, you can use the formula:

Cost = $40 + ($12 per hour) * X

Where X represents the number of hours.

For example, let's say you want to rent a canoe for 3 hours. The cost would be:

Cost = $40 + ($12 per hour) * 3
= $40 + $36
= $76

So, it would cost $76 to rent a canoe for 3 hours.
