| isida | MRP = marginal revenue x marginal product = [(1000 - 600)/4] x 4 |
| stefdunk | MRP = MP x P, or (10-6) x $100 |
| ilgibe | we are supposing MR = P, thus perfect competition.. |
| YOUCANDOIT | good point ilgibe! |
| fangluez | when # of hours increased from 7 to 8, the # of output increased is 4. Therefore marginal product (MP) = 4. MR = Price = $100 MRP = MR x MP = 100 x 4 = 400 |
