I need help figuring out what the cost per unit is. I have tried to calculate the weighted cost and using the cost in the required information section but I cant seem to figure it out.

! Required information Use the following information for the Exercises 3-7 below. (Algo) (The following information applies to the questions displayed below.) Laker Company reported the following January purchases and sales data for its only product. The Company uses a periodic inventory system. For specific identification, ending inventory consists of 220 units, where 180 are from the January 30 purchase, 5 are from the January 20 purchase, and 35 are from beginning inventory. Date Activities Jan. 1 Beginning inventory Jan. 10 Sales Jan. 20 Purchase Jan. 25 Sales Jan. 30 Purchase Totals Units Acquired at Cost Units sold at Retail 150 units @ $6.00 = $ 900 90 units @ $15.00 70 units @ $5.00 = 350 90 units @ $15.00 180 units @ $4.50 = 810 400 units $2,060 180 units Exercise 5-5A (Algo) Perpetual: Inventory costing LO P3 1. Complete the table to determine the cost assigned to ending inventory and cost of goods sold using specific identification. 2.
