text: deer valley lodge, a ski resort in the wasatch mountains of utah,? deer valley lodge, a ski resort in the wasatch mountains of utah, has plans to eventually add five new chairlifts. suppose that one lift costs $2 million, and preparing the slope and installing the lift costs another $1.3 million. the lift will allow 300 additional skiers on the slopes, but there are only 40 days a year when the extra capacity will be needed. (assume that deer park will sell all 300 lift tickets on those 40 days.) running the new lift will cost $500 a day for the entire 200 days the lodge is open. assume that the lift tickets at deer valley cost $55 a day and the added cash expenses for each skier-day are $5. the new lift has an economic life of 20 years ok.  now i have done all that assumption, what is it exactly that you would like to know?  fyi, i like the name of the lodge.  i would go there with my kids.  if they were big enough to ski.
