Answer:
C) is experiencing an economic profit of $40.
Step-by-step explanation:
Heath's total revenue = 30 units x $8 per unit = $240
average variable cost = $5 per unit, total variable costs = 30 x $5 = $150
total fixed costs = $50
currently Heath is making an economic profit = $240 - $150 - $50 = $40
since the question doesn't tell us anything about Heath's marginal costs, we cannot know if it should expand its production or not. Profits are maximized when marginal costs = marginal revenue ($8).
