9.The table below shows the total cost of cleaning classrooms.This is a continuation of the problem above.Use the numbers from the table above if you need them.

Helpful Formulas:TC = FC + VC.Fixed Costs are our costs if we produce 0.

Average X = X / QExample:AVC = VC / Q.We don't have average costs at 0 (can't divide by 0)

Marginal X = change in X / change in Q.We don't have marginal costs at 0.

(We didn't increase from anything to get to zero, so it wouldn't make sense.)

Note:Marginal Total Cost is the same thing as Marginal Variable Cost (fixed costs don't change, so variable costs are the only thing changing).We only have 1 marginal cost.
