The Quinn Corporation shows the following income statement. The firm uses FIFO inventory accounting. a. Assume that the same 11,200 unit volume is maintained in 20XY, but the sales price increases by 10 percent. Because of FIFO inventory policy, old inventory will still be charged off at $7.50 per unit. Also assume that selling and administrative expense will be 6 percent of sales and amortization will be unchanged. The tax rate is 34 percent. Compute aftertax income for 20XY. (Do not round the intermediate calculations. Round the final answer to nearest whole dollar.) $ b.
