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.

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
