Use the fоllоwing infоrmаtion to аnswer the next 6 questions. Fred’s Lаndscaping purchases bags of gravel from Barney’s Gravel Pit. These only sell during the summer season, and because of Barney’s long lead times there is only one chance to place an order. Fred’s gravel demand distribution, based on data from past summers, follows a normal distribution with µ = 2,400 and σ = 400. Fred pays Barney $18 per bag for gravel, and then sells it to his customers for $34 per bag. If any bags are left over on September 1, Fred sells them to the local college for $10 per bag. Finally, Barney’s production costs are $12 per bag.
