The cost to tend a boat is $10. There is also a charge of $2 for each person. Which expression represents the total cost to rent a boat for p persons?

(total cost) = (cost to tend a boat) + (price per person) * (number of people)

(total cost) = C

(cost to tend a boat) = 10

(price per person) = 2

(number of people) = p

C = 10 + 2p

or

C = 2p + 10
