Please show all work! I don't understand where the numbers are coming from from the previous

You are thinking about becoming a Paradise Coffee franchisee. Franchisees are offered a business specializing in producing an exclusive line of exotic coffee drinks (similar to Starbucks). Franchisees have had good success in towns without a Starbucks (Paradise franchises gross $220,000 sales on average per year). You will have to pay Paradise Coffee, Inc., a franchise fee of $3,000 a year plus 2.5% of gross sales. You will also also pay an annual National advertising fee of 3% of gross sales. Paradise requires that you use their logo-imprinted goods (plates, cups, napkins). They are purchased in bulk from Paradise and will cost you $40,000 per year. You also have to use their special Paradise coffee beans, which cost $12.00 per pound. You estimate you will use 400 pounds of beans a year. Other food ingredients (syrups, biscotti, whipped cream, soft drinks, etc) will cost $18,000 a year. You will have to hire three workers for a total annual cost will be $70,000. Other annual costs are utilities $4,800; rent $12,000; and liability insurance $6,000. You will have to invest $80,000 of your savings (presently earning 4% per annum) and borrow another $60,000 (on which you will pay explicit interest of $2500 a year). Note: neither the amount of the bank loan nor the $80,000 of your own money you invest is an explicit or implicit cost. However, the interest paid on the bank loan is explicit and the interest foregone on your savings is implicit. You are presently employed as an assistant manager at Little Nero Salads earning $45,000 a year (a job you will have to quit to go into Paradise Coffee). Moreover, you (implicitly) believe you should be able to earn $10,000 more than Little Nero is presently paying you.
