Suppose you are the marketing manager of a firm, and you plan to introduce a new product to the market. You have to estimate the first year net profit, which depends on several variables • Sales volume (in units) • Price per unit • Unit cost . Fixed costs Your net profit is net profit = sales volume x (price per unit-unit cost) - fixed cost The fixed cost is $120, 000, but other factors have some uncertainty. Based on your market research, there are equal chance that the market will be slow, ok, or hot. • Slow market the sales volume follows Poisson distribution with mean 50,000 units product, and the average price per unit is $11.00 ● Ok market the sales volume follows Poisson distribution with mean 75,000 units product, the average price per unit is $10.00 Hot market: the sales volume follows Poisson distribution with mean 100,000 units product, but the competition is severe so you expect the average price per unit is just $8.00 No matter what the market type is, your average unit…
Linear Modeling 1. Some phone apps measure the number of steps taken during a period of time. John downloaded an app that reported data in a table like this: Time Steps Steps taken taken (minutes) 600 4000 20 2400 25 3000 4200 3000 35 2000 1000 10 20 30 40 Minutes (a) What are the variables of the problem? Identify independent and/or dependent variables of the problem if any. (b) Use the information from the table to graph the number of steps that John has taken over time. Connect the points on your graph. Does this curve or is it a line? (c) Explain why the graph tells you that John is walking at a constant pace.

*NEED HELP WITH 1, 2, and 3*DYNAMIC INVENTORY MODELSPLEASE WALK THROUGH WITH EXCEL IF POSSIBLE, PLEASE!Mohawk Industries builds transmissions for a large automobile manufacturer. One of its transmissionassemblies requires part #HD234, purchased from a supplier within the same industrial park. Because ofthe close proximity of its supplier, the lead me for part #HD234 is negligible.The demand for part #HD234 varies according to the orders received from the automobile manufacturer.The requirements schedule for the next 10 periods is shown below: Period 1 2 3 4 5 6 7 8 9 10 Total Demand 115 50 175 95 150 225 75 70 40 20 1,015 This requirements schedule is considered fairly typical. Furthermore, the cost of placing an order with anearby supplier is $85.00, the purchase cost is $65.00, and the holding cost fracon is 0.01 per period.Mohawk is in the process of assessing different lot-sizing policies. It is interested in several that havebeen suggested.Before it can decide among them,…
