To calculate the maximum revenue, we need to determine the price that will generate the most sales. Let's calculate the revenue for different prices:
| Price | Number of Items Sold | Revenue |
|-------|---------------------|----------|
| 50 | 620 | 31000 |
| 51 | 610 | 31110 |
| 52 | 600 | 31200 |
| 53 | 590 | 31270 |
| 54 | 580 | 31320 |
| 55 | 570 | 31350 |
| 56 | 560 | 31360 |
| 57 | 550 | 31350 |
| 58 | 540 | 31320 |
| 59 | 530 | 31270 |
| 60 | 520 | 31200 |
| 61 | 510 | 31110 |
| 62 | 500 | 31000 |
As we can see from the table, the maximum revenue is $ 31,350 and it occurs when the price is $ 55. Therefore, the maximum revenue possible in this situation is 31350.
