Joseph has patented a technique that preserves fresh floral arrangements so they can be stored or displayed for at least five years while maintaining their beauty. The chemical preservation material and variable overhead costs run $6 and $10 per bouquet, respectively. Customers can bring in their own arrangements, or Joseph can purchase fresh bouquets from a variety of florists at a reduced price. Fixed production costs include depreciation on the equipment of $2,300 per year and other operating expenses of $3,200 per year
