A high school club is researching a tour package offered by the Island Kayak Company. The company charges $35 per person and $245 for the tour guide. Which function represents the total cost, C(x), of this kayak tour package for x club members?

• C(x) = 35x

• C(x) = 35x + 245

• C(x) = 35(x + 245)

• C(x) = 35 + (x + 245)
