To compute the total revenue for Q=16, we would take price (54 dollars) times 16 units sold to get 16*54= 864 dollars of revenue. To compute the marginal revenue, since we previously earned 0 revenue when we sold 0 units, we would simply take 866/ 16 units to get an increase of 54 dollars of revenue per unit. This is no coincidence- when a firm faces a constant price, marginal revenue will always equal price. To get profit, take revenue minus cost. Total cost is 1180, so we earn 864-1180 = -316 dollars of profit , or a loss of 316 dollars. Per unit, this is -316/16 = -19.75. The calculations are identical for Q=40- see if you can do it now!
