The data given in the table to the right are for Lane, the only vendor of brick oven baked goat
cheese and avocado pizzas at a sporting event. Q is the number of pizzas sold each hour, P is the price in dollars and TR is the total revenue (just P X Q). If the vendor determines that her profit maximizing price per
pizza is $15 then her marginal cost for each pizza must be:
 over $6 but no more than $8.
 over $8 but no more than $10.
 over $10 but no more than $12.
 over $12 but no more than $14.
 over $14 but no more than $15.
