Hey there :)
Toby purchased 5 tickets → each cost $12 → with $3.50 service cost
5 × 12 = $60
$60 + $3.50 = $63.50
Your answer will be option I) $63.50
gives an average cost per unit, if we want to produce x of them.
So for example, we want to produce 500 toy cars for our store, and we need a price per unit (per 1 toy car). What we do is we calculate C(500).
So to calculate the cost of one unit when producing 1250, we calculate C(1250)
$ is the cost of 1 toy car.
