Ive tried to donthis my self but im getting something wrong. HELP.

Crane Enterprises uses a periodic inventory system for buckets it sells. It had a beginning inventory on April 1 of 72 units at a cost of $6 per unit. During April, the following purchases and sales were made. \begin{tabular}{ccc} & \multicolumn{2}{c}{ Sales } \\ April 5 & 124 & units at $20 \\ 11 & 94 & units at $20 \\ 20 & 84 & units at $20 \\ 30 & 42 & units at $20 \\ & 344 \end{tabular} Compute the April 30 ending inventory and April cost of goods sold under (a) average cost, (b) FIFO, and (c) LIFO. (Round cost per unit to 2 decimal places, es. 15.25 and final answer to 0 decimal places, e.g. 1,525.)
