Hi! I'm having some trouble with this problem! A small convenience store pays $100 for a constant supply of shampoo bottles. 20 bottles are shipped to the small business. The convenience store then purchases 30 bottles of conditioner for $6 per bottle. What is the fixed and variable cost for the shampoo and conditioner bottles combined? The discount rate is 12%. I was thinking that the $100 was the fixed cost... but I feel like that isn't right. I'm not really sure where to start on this problem. Usually for these problems I put them into a graph in excel and just use y=mx+b to find the fixed and variable cost, but I'm not sure how to do that with this information. Also, is the discount rate important in this problem or was that thrown in there to confuse me? Thanks!
