Variable costs, fixed costs, relevant range. Gummy Land Candies manufactures jaw-breaker candies in a fully automated process. The machine that produces candies was purchased recently and can make 5,000 per month. The machine costs $6,500 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. Gummy Land currently makes and sells 3,900 jaw-breakers per month. Gummy Land buys just enough materials each month to make the jaw-breakers it needs to sell. Materials cost 40¢ per jaw-breaker. Next year Gummy Land 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.
