Answer

Explanation:

Step1: Recall profit - maximization condition

Profit is maximized when marginal revenue (MR) equals marginal cost (MC). Calculate the marginal revenue and marginal cost values for each quantity. Marginal revenue for quantity $n$ is $MR_n=TR_n - TR_{n - 1}$ (where $TR$ is total revenue), and marginal cost for quantity $n$ is $MC_n=TC_n - TC_{n - 1}$ (where $TC$ is total cost). For quantity 1: $MR_1=9 - 0=9$, $MC_1=8 - 2 = 6$ For quantity 2: $MR_2=16 - 9 = 7$, $MC_2=13 - 8=5$ For quantity 3: $MR_3=21 - 16 = 5$, $MC_3=17 - 13 = 4$ For quantity 4: $MR_4=24 - 21=3$, $MC_4=20 - 17 = 3$ For quantity 5: $MR_5=25 - 24 = 1$, $MC_5=22 - 20=2$ For quantity 6: $MR_6=24 - 25=- 1$, $MC_6=28 - 22 = 6$ Profit - maximization occurs at quantity 4 where $MR = MC=3$.

Step2: Find total revenue and total cost at profit - maximizing quantity

At quantity $q = 4$, from the table, total revenue $TR = 24$ and total cost $TC = 20$.

Answer:

total revenue equals $24 and total cost equals $20
