Assume a company worked on four jobs during June: Jobs W, X, Y, and Z. At the end of June, the job cost sheets for these four jobs contained the following data: Jobs X, Y, and Z were completed during June. Job W was incomplete at the end of June. There was no finished goods inventory on June 1 and the company's total manufacturing overhead applied always equals its total actual manufacturing overhead. If the cost of goods sold in June is $450, how many units from Job Z must have been sold in June
