1. TenAlpina is adding a new product line, which will add some new revenues and costs. Based on Guilias estimates, and assuming that the volumes for piton production and sales do not change, how many wall hammers would TenAlpina Tools have to sell in order the same annual gross margin (in dollars) as it would have if only piton were sold? That is, at what demand level for hammers would Guilia be indifferent (from a total profitability point of view) as to whether or not to add the new product line?
