Mannisto Inc. uses the FIFO inventory cost flow assumption. In a year of rising costs and prices, the firm reported net income of $286,163 and average assets of $1,487,690. If Mannisto had used the LIFO cost flow assumption in the same year, its cost of goods sold would have been $32,610 more than under FIFO, and its average assets would have been $34,640 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 (i.e., 12.2%).) FIFO LIFO ROI % b. Suppose that two years later costs and prices were falling. Under FIFO, net income and average assets were $323,883 and $1,832,020, respectively. If LIFO had been used through the years, inventory values would have been $40,080 less than under FIFO, and current year cost of goods sold would have been $20,408 less than under FIFO. Calculate the firm's ROI under each cost flow assumption (FIFO and LIFO). (Enter your answers as percentages rounded to 1 decimal place (i.e., 12.2%).)
