Northwood Company manufactures basketballs. The company has a ball that sells for $25. At present, the ball is manufactured in a small plant that relies heavily on direct labor workers. Thus, variable costs are high, totaling $15 per ball, of which 60% is direct labor cost. Last year, the company sold 30,000 of these balls, with the following results: Sales (30,000 balls) $750,000 Variable expenses 450,000 Contribution margin 300,000 Fixed expenses 210,000 Net operating income $90,000 Due to an increase in labor rates, the company estimates that variable costs will increase by $3 per ball next year. The president feels that the company must raise the selling price of its basketballs. If Northwood Company wants to maintain the same CM ratio as last year, what selling price per ball must it charge next year to cover the increased labor costs
