C. As you look over the completed table, what level of Q maximizes profit when price=$60 and when price=$50?
Total Revenue = Price x Quantity
Marginal Revenue = Change in Total revenue / Change in Quantity
Marginal Cost = Change in Total Cost / Change in Quantity
Profit = Total Revenue - Total Cost
| Q | P | TR | MR | TC | MC | Profit | 
| 0 | 60 | 0 | -- | 100 | -- | -100 | 
| 1 | 60 | 60 | 60 | 150 | 50 | -90 | 
| 2 | 60 | 120 | 60 | 178 | 28 | -58 | 
| 3 | 60 | 180 | 60 | 198 | 20 | -18 | 
| 4 | 60 | 240 | 60 | 212 | 14 | 28 | 
| 5 | 60 | 300 | 60 | 230 | 18 | 70 | 
| 6 | 60 | 360 | 60 | 250 | 20 | 110 | 
| 7 | 60 | 420 | 60 | 272 | 22 | 148 | 
| 8 | 60 | 480 | 60 | 310 | 38 | 170 | 
| 9 | 60 | 540 | 60 | 355 | 45 | 185 | 
| 10 | 60 | 600 | 60 | 410 | 55 | 190 | 
From the above table, the firm's achieves maximum profit at 10 units of 190
| Q | P | TR | MR | TC | MC | Profit | 
| 0 | 50 | 0 | -- | 100 | -- | -100 |

| 10 | 50 | 500 | 50 | 410 | 55 | 90 | 
From the above table, the firm's achieves maximum profit at 9 units of 95
