Question

Part 2

You are a producer of potatoes. You have to decide whether to sell your crop now or store it and sell later. You have just harvested your crop and the current market price is $30 per cwt. You have enough storage capacity for your entire crop and your storage cost per cwt. is defined by:

SC$ = 0.25 + .1T²

where T = 1,..N the number of months in storage, T = 1…11. You can only keep your potatoes in storage until the new crop is harvested.

The sales price for potatoes changes through time according to a premium over the price at harvest time in the following table. You will note that this premium starts to decline at some point, because of the deterioration in the quality of stored potatoes.

Time	Market Price Premium ($)	Market price ($)	Storage cost ($)	Net sales price ($)
Harvest (Month 0)	0	30	0	30
Month 1	1
Month 2	2
Month 3	3
Month 4	4
Month 5	5
Month 6	6
Month 7	7
Month 8	7
Month 9	5
Month 10	3
Month 11	1

1. Calculate the market price and the storage cost in each month and put these in the table. Calculate the net sales price for each month.

2.Which is the most profitable month for selling the stored potatoes? Explain.

3.Which is the last month in which you make a positive return from storing potatoes? Explain.
