Anna11 [10]

Answer:

a. 80,000 units

b. 95,000 units

Explanation:

The computation is shown below:

a.The anticipated break-even sales (units) is

= ($27,600,000 + $5,175,000) ÷ $345    

= $32,775,000 ÷ $345    

= 95,000 units

Cost of goods sold equal:

Opening/beginning inventory plus purchases minus closing/ending inventory

Cost of goods sold minus plus purchases plus closing/ending inventory.

Cost of sales is $470,000

Purchases is $415,000

Ending inventory is $160,000

Therefore, beginning inventory at January 1, 2018 is
