Hardware Inc. has a periodic inventory system and uses the weighted average method. The company began the year with 150 large brass switch plates on hand at a cost of $4.00 each. Purchases of switch plates during the year were as follows:

Date of Transaction	Quantity Received	Unit Cost
May 7	200	$4.20
June 11	200	$4.40
November 22	250	$4.80

The switch plates sell for $7.00 each. If Hardware sells 570 switch plates during the year, what is the company's cost of goods sold?
