Answer:
$495,500
Step-by-step explanation:
First, we calculate the total number of books sold during the quarter.
950,000/50 = 19,000 books sold
Then we calculate variable selling and administrative expenses.
Variable Selling Expenses = 19,000 x 4 = $76,000
Variable Administrative Expenses = 950,000 x 3% = $28,500
Finally, we calculate contribution margin for the first quarter by deducting Cost of Goods Sold, Variable Selling Expenses and Variable Administrative Expenses from the Total Sales Value, as shown below:
950,000 - (350,000 + 76,000 + 28,500) = $495,500
The contribution margin for Sam's Bookstore for the first quarter is: $495,500
