You see a niche in the market for hobby home gardeners who want a vegetable patch but are discouraged when their seeds don't grow. You have set up an online store, with free delivery (you and your van) to deliver seedlings in the early summer to your customers. The only problem is that you have to estimate how many seedlings will be sold for each type of vegetable during the summer season and these need to be grown for at least one month in advance in a pot. This year, for runner beans, you expect the summer season demand to be normally distributed with an expected demand of 500 and a standard deviation of 40. You plan to sell the seedlings for $3.50 each, and the cost to grown them is $0.5 (for the pot and the soil). If you do not sell them, you have to just plant them somewhere: there is no salvage value. For the following questions, please use the Normal Tables with the z value given to two decimal places and the round up rule (pick the z value to give you the larger order quantity). How many runner bean seedlings should you grow in order
