Mannisto Inc uses the FIFO inventory cost flow assumption. In a year of nising costs and prices, the firm reported net income of $261,694 and average assets of $1,516,390, If Mannisto had used the LIFO cost flow assumption in the same year, its cost of goods sold would have been $38,700 more than under FIFO, and its average assets would have been $43190 less than under fifo, Required: a. Calculate the firm's ROI under each cost flow assumption (FIFO and LIFO), (Enter your answers as percentages rounded to 1 decimal place (ie., 12.2%).) FIFO LIFO ROI % % b. Suppose that two years later costs and prices were falling. Under FIFO, net income and average assets were $316,434 and $1.863.470, respectively. If LIFO had been used through the years, Inventory values would have been $40.790 less than under FIFO, and current year cost of goods sold would have been $17,560 less than under FIFO. Calculate the firm's ROF under each cost flow assumption (FIFO and LIFO). (Enter your answers as percentages rounded to 1 decimal place (i.e., 12.2%) FIFO LIFO ROI
