Bowling costs $4.50 per game (g). Shoe rental costs $3.75 each. The total cost is a function of the number of games. What function rule models the total cost of games and shoe rental? Evaluate the function for three games.

Respuesta :

let x = number of games, let y = cost of shoe rental   then        Total cost = x•$4 + y   In this case, TC = 3•$4 + $2   TC = $14

The cost function is an illustration of linear functions

  • The cost function is [tex]C(x) = 3.75 + 4.50x[/tex]
  • The cost for three games is $17.25

From the question, we have:

[tex]G = 4.50[/tex] --- cost per game

[tex]R = 3.75[/tex] --- cost per shoe rent

Since the cost is a function of number of games, it means that;

The cost of shoe rent is a fixed cost

Let x represents the number of games.

So, the cost function is:

[tex]C(x) = R + G \times x[/tex]

This gives

[tex]C(x) = 3.75 + 4.50 \times x[/tex]

[tex]C(x) = 3.75 + 4.50x[/tex]

Substitute 3 for x; to evaluate the function for 3 games

[tex]C(3) = 3.75 + 4.50 \times 3[/tex]

[tex]C(3) = 3.75 + 13.50[/tex]

[tex]C(3) = 17.25[/tex]

Hence, the cost for three games is $17.25
