Question

John is at the beach and he wants to rent a JetSki and beach chairs for the day the following function represents the cost for each where J(x) represents the cost of the Jet ski and B(x) represents the cost of the beach chairs

Answer 1

The function, j(x) represents the cost of the Jet ski and B(x) represents the cost of the beach chairs. If j(x) = 30x + 7 and B(x) = 5x + 3

The total cost, C(x) for the rntals at the beach would be the sum of both costs. It becomes

C(x) = 30x + 7 + 5x + 3

Collecting like terms, we have

C(x) = 30x + 5x + 7 + 3

C(x) = 35x + 10

The first option is correct
