4. Brielle Company recently incurred $420,000 total variable expenses and $125,000 total fixed costs when it produced 40,000 units of its product. Brielle received a special purchase order from a company in Denmark for another 11,000 units at a reduced sales price of $11 per unit. There is enough capacity to fill the order, so fixed costs will not change if the order is accepted. However, the order will require Brielle to pay an 8% export tariff (tax) based on the sales revenue (price) per unit. Prepare a differential analysis that shows whether Brielle should reject or accept the purchase offer from the Danish company
