2-23 Variable costs, fixed costs, relevant range. Sweetum Candies manufactures jaw-breaker candies in a fully automated process. The machine that produces candies was purchased recently and can make 4,100 per month. The machine costs $9,000 and is depreciated using straight line depreciation over 10 years assuming zero residual value. Rent for the factory space and warehouse, and other fixed manufacturing overhead costs total $1,200 per month. Sweetum currently makes and sells 3,800 jaw-breakers per month. Sweetum buys just enough materi- als each month to make the jaw-breakers it needs to sell. Materials cost 30 cents per jawbreaker. Next year Sweetum expects demand to increase by 100%. At this volume of materials purchased, it will get a 10% discount on price. Rent and other fixed manufacturing overhead costs will remain the same. Required 1.
