you just learned about break even analysis and you are wondering how many t-shirts you have to sell in your t-shirt business to break even each month. you jot down the following information about your business: your t-shirt business is booming. you sell creatively designed t-shirts for $20 each and you have been selling out all 500 you make each month. $10,000 a month in revenue and you are starting to think about expanding by increasing production already. you took this business class though and learned about break-even and one night you decide to see how many t-shirt you are selling above your break-even. so you write down the following financial details: 1. each month you buy 500 blank t-shirts for a total of $1,500 delivered to your warehouse. 2. you have a month to month lease on the warehouse for $600/mo. 3. you have one employee who does all the design and t-shirt printing. he works full time for you and you pay him $2,300 a month. 4. you've been spending $500 on t-shirt ink each month to get all 500 t-shirts each month ready for sale. 6. your other expenses (electricity, internet, phone) add up to $300 more each month. how many t-shirts do sell above your break-even number?
