I don't see a solution for this problem with weighted average cost. Any help would be much appreciated!!

During the year, Wright Company sells 375 remote-control airplanes for $110 each. The company has the following inventory purchase transactions for the year.

Date	Transaction	Number of Units	Unit Cost	Total Cost
Jan. 1	Beginning inventory	60	$76	$	4,560
May 5	Purchase	220	79		17,380
Nov. 3	Purchase	140	84		11,760
		420		$	33,700

Calculate ending inventory and cost of goods sold for the year, assuming the company uses weighted-average cost. (Round your average cost per unit to 4 decimal places.)
