Note:
Snacks are only $5, and is a one-time payment.
Renting a paddle boat is $4 per hour. Let hour = h
You have $13 in all
13 = 4h + 5
Isolate the h. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
Subtract 5 from both sides
13 (-5) = 4h + 5 (-5)
4h = 13 - 5
4h = 8
Divide 4 from both sides
(4h)/4 = (8)/4
h = 8/4
h = 2
2 hours is your limit for the amount of hours you can ride with $13 and after buying snacks.
