Answer:
$124,200
Step-by-step explanation:
Sales revenue = $98 * 1,800 = $176,400
Total variable costs = Total variable manufacturing costs + Total variable marketing costs = ($23 * 1,800) + ($6 * 1,800) = $ 52,200
Contribution margin using variable cost = Sales revenue - Total variable costs = $176,400 - $52,200 = $124,200.
