Product cost per kayak totals $475, which consists of $375 in variable production cost and $100 in fixed production cost—the latter amount is based on $102,500 of fixed production costs allocated to the 1,025 kayaks produced. The $230,000 in selling and administrative expense consists of $85,000 that is variable and $145,000 that is fixed.
