Answer:
$65.00 total, $32.50 each
Explanation:
We can model the cost of renting a canoe with the expression y = 25 + 5x, where x is the number of hours spent canoeing and y is the total cost.
Since Tommy and his friend spent 8 hours canoeing, we'll plug that in to x and solve.
y = 25 + 5(8)
y = 25 + 40
y = 65
This means the total cost of the trip is $65.
If they decide to split this cost between the two of them, they will each pay $32.50 as 65/2 = 32.5.
