hello, I need to answer questions 1-5 based on the scenerio. please give me explanations on the answers, especially question #5. I have to be able to explain how I got each answer. thank you!

During a Skype session with Jordan and Taylor, you mention that your current cost model in accounting is break-even analysis. They are not following your explanation, but they say they will swing by with some brownies for a discussion. More brownies! This is paying off, except for those extra pounds. Selling price to Yumminess at $10 per tin. The cost is $8 per tin, which includes $6 of direct material and $1.50 of direct labor. Annual manufacturing overhead is estimated at $100,000 for the expected sales of 200,000 tins. Operating expenses are projected to be $80,000 annually. After looking over the costs for manufacturing overhead and operating expenses, you approximate that 85% of manufacturing overhead and 20% of operating expenses are variable costs. 1. What is the TOTAL fixed cost? (4 points) 2. What is the TOTAL variable cost? (4 points) 3. What is the contribution margin per UNIT? (Do not round.) (4 points) 4. How many units are necessary to reach break-even? (Always round up to the next unit for break-even, since you cannot sell a partial unit.) (4 points) 5. Jordan is concerned that they will not be able to sell 200,000 tins of brownies. Given 200,000 tins as their expected sales level, what is the decrease of total sales dollars that they endure before they incur a net loss? (4 points)
