you run a business out of your dorm room selling WHBC textbooks in both paper and digital versions. The paper version costs you $100 and you can sell it for $200. The digital version costs you $60 and you can sell it for $100

last semester you sold 20 paper versions for $4000 and 120 digital versions for $12,000. You expect that sales mix will continue this semester.

if your semester fixed cost are $4250 for a publisher's license, what dollar amount of sales will you need to break-even?

how many paper and digital books will you have to sell to break-even ( hint-you will have a partial paper book)
