BBG Corporation manufactures a synthetic element, pixie dust. Management was surprised to learn that income before taxes had dropped even though the sales volume had increased. Steps had been taken during the year to improve profitability. The steps included raising the selling price by 12% because of a 10% increase in production costs, and instructing the selling and administrative departments to spend no more this year than last year. Both changes were implemented at the beginning of the year.
BBG's accounting department prepared and distributed to top management the comparative income statements and related financial information that follow (BBG uses the FIFO inventory method for finished goods):

Instructions
(a) Explain to management why net income decreased despite the increases in sales price and sales volume.
(b) It has been proposed that the company use variable costing for its internal reporting. Prepare the variable-costing income statement for 2016.
(c) Reconcile the difference in income before taxes using the absorption- costing method currently used by BBG and the variable-costing method proposed for 2016.
