Alliance Enterprises is considering extensively modifying their manufacturing equipment. The modifications will result in less wastage of materials, which will reduce variable manufacturing costs and introduce changes to the production process that will improve product quality. This will allow Alliance to increase the selling price of the product. Annual fixed costs are expected to increase to $990,000 if the modifications are made. Expected fixed and variable costs as well as the selling prices are shown below: Existing Modified Cost Item Equipment Equipment Selling price per unit S 8 10 Variable cost per unit Fixed costs 480,000 990,000 Required: 1.
