Complete the table given the formulas MC = ATC / Delta Q and TC = TFC + TVC.

• For $Q=0$: $TC = 100 + 0 = 100$
• For $Q=1$: $TC = 100 + 30 = 130$
• For $Q=2$: $TC = 100 + 70 = 170$
• For $Q=3$: $TC = 100 + 120 = 220$
• For $Q=4$: $TC = 100 + 180 = 280$

Marginal Cost is the change in total cost when quantity increases by one unit.

• For $Q=1$: $MC = \frac{130 - 100}{1 - 0} = \frac{30}{1} = 30$
• For $Q=2$: $MC = \frac{170 - 130}{2 - 1} = \frac{40}{1} = 40$
• For $Q=3$: $MC = \frac{220 - 170}{3 - 2} = \frac{50}{1} = 50$
• For $Q=4$: $MC = \frac{280 - 220}{4 - 3} = \frac{60}{1} = 60$
