Classifying Costs

Consider the pizza chain Blaze Pizza. It custom builds and cooks each pizza to order. Items $1-5$ represent cost activities associated with a particular store.

$1.$ Pepperoni on the pizza

$2.$ Wood to fuel the fire used to cook the pizzas $($assume that ovens are maintained at the same temperature during business hours$)$

$3.$ Insurance on the building

$4.$ The labor costs for the employee building and cooking each pizza

$5.$ The costs associated with employees taking pizza orders

Relative to the pizzas, classify each cost activity above as variable or fixed AND direct or indirect.
