On December 31 of last year, Wolfson Corporation had in inventory 610 units of its product, which cost $18 per unit to produce. During January, the company produced 1,010 units at a cost of $21 per unit. Assuming that Wolfson Corporation sold 1,120 units in January, what was the cost of goods sold (assume FIFO inventory accounting)? (Omit the "$" sign in your response.)
