Question 2
A civic organization cooks and serves pancakes once a year as a fundraiser and has done so for the past 25 years. The pancake grill size requires pancakes to be cooked in advance of the orders for them. All labor is donated, but the electricity and pancake supplies cost 0.20 per pancake. Each pancake sells for 0.60 . From past records it appears that the distribution of pancake sales is approximately normal with a mean of 3000 and a standard deviation of 450 . Cooked, but unsold pancakes are given to anyone who wishes to take them. Find the number of cooked pancakes that will yield the maximum profit for the project. ___________________ _ pancakes Remove all commas from your answer before submitting.
