Answer:
$144,000
Explanation:
Sales $900,000
Less Variable expenses:
Cost of goods sold $630,000
Variable selling $90,000
($900,000 ÷ $50 per book = 18,000 books)
($5 per book x 18,000 books)
Variable administrative $36,000
(4% of $900,000)
Total Variable expenses $756,000
Contribution margin $144,000
($900,000-$756,000)
Therefore the Contribution margin for Sam's Bookstore for the first quarter is $144,000
