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 Jx represents the cost class=

Respuesta :

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
