Looking to solve for the precent% here

Calculate ending inventory, cost of goods sold, gross profit under each of the following methods. (1) LIFO. (2) FIFO. (3) Average- cost. (Round average-cost method answers to 2 decimal places, e.g. 1,250.25 and other answers to 0 decimal places, e.g. 1,250. Use weighted-average unit cost rounded to 2 decimal places for computations.) LIFO FIFO AVERAGE-COST The ending inventory $ 3,628 $ 4,046 $ 3,820.96 The cost of goods sold $ 7,228 $ 6,810 $ 7,035.04 Gross profit $ 4,285 $ 4,703 $ 4,477.96 Part 3 Calculate gross profit rate under each of the following methods. (1) LIFO. (2) FIFO. (3) Average-cost. (Round answers to 1 decimal place, e.g. 51.2%.) LIFO FIFO AVERAGE-COST Gross profit rate % % %
