D.) Marginal cost is equal to average total cost. (Because when the average total cost is at its minimum, marginal cost is also at its minimum.)
Answer:
(A) $425,000
(B) $24,350
Explanation:
(a) Average Operating Assets:
= (Beginning Operating Assets + Ending Operating Assets) ÷ 2
= ($390,000 + $460,000) ÷ 2
= $425,000
Therefore, the average operating assets is $425,000.
(b) Residual Income:
= Operating Income - (Minimum Rate of Return × Average Operating Assets)
= $66,850 - (10% × $425,000)
= $66,850 - $42,500
= $24,350
