Zimmerman Company had 2,000 units of their product on hand on April 1, 2019 at a cost of $21/unit.  Zimmerman had purchases on April 9th (2,000 units at $22/unit) and April 17th (3,500 units at $23/unit).  On April 20th, Zimmerman sold 4,000 units of their product.  Assuming Zimmerman uses a perpetual inventory system and accounts for inventory using the FIFO method, what amount of cost of goods sold will Zimmerman report in conjunction with the sale on April 20th?
