The entrance fee to a local waterpark is $28 per person. At the waterpark, you can rent a raft for $2.50 per hour. Which expression is equivalent to the amount it would cost Colton for h hours in the park if he rented a raft?
The cost to rent a raft for h hours is $2.50 per hour, so the cost for h hours is 2.50*h = $<<2.5*h=2.5h>>2.5h.
The entrance fee is $28, so the total cost for h hours in the park, including the entrance fee, is $28 + $2.5h.
The equivalent expression is 28 + 2.5h. Answer: \boxed{28+2.5h}.
