Sunland uses the FIFO cost flow assumption. All purchases and sales are on account. (a) Assume Sunland uses a periodic system. Prepare all necessary journal entries, including the end-of-month closing entry to record cost of goods sold. A physical count indicates that the ending inventory for January is 111 units. (If no entry is required, select "No entry" for the occount titles and enter 0 for the amounts. Credit occount titles are outomotically indented when amount is entered. Do not indent manually. List all debit entries before credit entries.)
