You plan to open a small business for manufacturing pet collars, leashes, and harnesses. You have found a workshop space you can use for sewing your products. After some research and planning, you have estimates for the various operating costs for your business.

The total square footage for the sewing rooms is 1,500 square feet broken into three areas (500 square feet each). You have taken out a loan for start-up costs, and the monthly payment is $550; it goes into effect immediately and should be accounted for in your costs. You will also collect a modest salary for the first year of $500 per month; remember to divide evenly among the services.

I really need help with the exact excel formulas for the above (=165/3), specifically the answers in blue. I feel pretty confident in the answers, but I'm struggling with how to articulate them in an excel formula format. Especially the Variable/Cost formulas. Please HELP!
