Jenny Jingle bell has always wished to own her own French macaroons shop. Ever since she tried her first macaroon, she thought it would be a brilliant idea to have her own shop where she can sell a multitude of flavors and colors of French macaroons. She purchased a premium site for the macaroons shop, right across the street from Campus Martius Park in Downtown Detroit. After extensive research, Jenny decided that it is best for her to open a franchise at first. The franchise that best fit Jenny's criteria is Franois Patisserie. A Franois Patisserie franchise costs $30,000, an amount that is amortized over 15 years. As a franchisee, Jenny needs to adhere to the company's building specifications. The building would cost an estimated $450,000 and would result in a $50,000 salvage value at the end of its 15 -year life. The equipment needed is sold as a package by the corporate office at a cost of $200,000, will have a salvage value of $10,000 at the end of its 5 -year life, equipment and must be replaced every 5 years. Jenny estimates the annual revenue from a Franois Patisserie franchise at $950,000. Food costs typically run 36% of revenue. Annual operating expenses, not including depreciation, total $425,000. For financial reporting purposes, Jenny will use straight-line depreciation and amortization. Based on past experience, she uses a 16% discount rate. Required: a.
