Burns Industries currently manufactures and sells 18,000 power saws per month, although it has the capacity to produce 33,000 units per month. At the 18,000-unit-per-month level of production, the per-unit cost is $61, consisting of $38 in variable costs and $23 in fixed costs. Burns sells its saws to retail stores for $78 each. Allen Distributors has offered to purchase 4,800 saws per month at a reduced price. Burns can manufacture these additional units with no change in its present level of fixed manufacturing costs. Assume that Allen Distributors offers to purchase the additional 4,800 saws at a price of $45 per unit. If Burns accepts this price, Burns' monthly gross profit on sales of power saws will:

A) Increase by $216,000.

B)Decrease by $158,400.

C) Decrease by $76,800.

D) Increase by $33,600.
