| danlan | Total revenue=Price*quantity |
| chamad | A is false because the firm may increase quantity |
| Thescholar | The trick here was to notice that the question refers to total revenue and not normal profit |
| thekobe | yes, revenue is related only to output, it does not includes costs, thats the trick |
| choas69 | if you make a mistake here you're learning, keep going. |
| MathLoser | TR = P x Q Example: P =$5 . Q = 10. 5 x 10 = 50. 5 x 11 = 55 (+10%) 5 x 12 = 60 (+9%) 5 x 13 = 65 (+8.3%) 5 x 14 = 70 (+7.69%) I'm lost with this question. |
| 10425406 | the rate is constant because the marginal increase in TR is 5 for every single increase in output/quantity |
