You are currently trying to decide between two cost structures for your business: one that has a greater proportion of short-term fixed costs and another that is more heavily weighted to variable costs. Estimated revenue and cost data for each alternative are as follows: Selling price per unit Variable cost per unit Short-term fixed costs per year Required: Cost Structure Alternative 1 Alternative 2 $ 50 35 55,000 $ 50 30 60,000 1. What sales volume, in units, is needed for the total costs in each cost-structure alternative to be the same? 2. Suppose your profit goal for the coming year is 10% of sales (i.e., operating profit/sales = 10%). What sales level in units is needed under each alternative to achieve this goal? 3. Suppose again that your profit goal for the coming year is 10% of sales. What sales volume in dollars is needed under each alternative to achieve this goal?
