formulas
TC = TFC + TVC, AC x Qty
AC = TC/Qty
TFC = TC - TVC
TVC = TC - TFC
AVC = TVC/Qty
AFC = TFC/Qty
BEQ = FC/ SP-VC
BEQ = FC/Contribution per unit
Contribution per unit = SP - VC
Total Contribution = Contribution per unit x Qty
Profit = Total Contribution - FC
Profit = TR - TC
TR = Price x Qty
Price = TR/Qty
MOS = Actual output - BEQ
