Donnelly Corporation manufactures and sells T-shirts imprinted with college names and slogans. Last year, the shirts sold for $7.50 each, and the variable cost to manufacture them was $2.25 per unit. The company needed to sell 20,000 shirts to break even. The after tax net income last year was $5,040. Donnelly's expectations for the coming year include the following:
• The sales price of the T-shirts will be $9
• Variable cost to manufacture will increase by one-third
• Fixed costs will increase by 10%
• The income tax rate of 40% will be unchanged. If Donnelly Corporation wishes to earn $22,500 in after tax net income for the coming year, the company's sales volume in dollars must?
