Comprehensive problem on unit costs, product costs.

If 2 kilograms of direct materials are used to make each unit of finished product,
100,000 units  2 kg, or 200,000 kg, were used at \$0.70 per kilogram of direct materials
(\$140,000 ÷ 200,000 kg). (The direct material costs of \$140,000 are direct materials used, not purchased.) Therefore, the ending inventory of direct materials is 2,000 kg 
\$0.70 = \$1,400

Average unit manufacturing cost:
\$233,000 ÷ 100,000 units = \$2.33 per unit
Finished goods inventory in units: \$20,970 (given) ÷ \$2.33 per unit = 9,000 units 3.

Units sold in 2013 = Beginning inventory + Production – Ending inventory

= 0 + 100,000 – 9,000 = 91,000 units Selling price per unit in 2013: \$436,800 ÷ 91,000 = \$4.80 per unit
