Answer:
$21 million
Step-by-step explanation:
Full cost = $10.3 million
Variable cost = 70.6% of full cost = 0.706 × $10.3 million = $7.2718 million
Inventory cost = 30% of full cost = 0.3 × $10.3 million = $3.09 million
Annual cost of carrying inventory investment = full cost + variable cost + inventory cost = $10.3 million + $7.2718 million + $3.09 million = $20.6618 million = $21 million (to the nearest dollar)
