Ikagami Retail receives shipments of a particular product from Booker Store and PaulEnterprises. Let x = number of units of product received from Booker Store y = number of units of products received from Paul Enterprises Requirement: a. Write an expression for the total number of units of products received by Ikagami Retail.b. Shipments from Booker Store cost P20 per unit, and shipments from Paul Ent cost P25 per unit. Develop an objective function representing the total cost of shipments to Ikagami.c. Assuming a monthly demand at Ikagami is 5,000 units, develop a constraint that requires 5,000 units to be shipped to Ikagami.d. No more than 4,000 units can be shipped from Booker, and no more than 3,000 from Paul. Develop constraints to model this situation.e. Of course, negative amounts cannot be shipped. Combine the objective function and constraints developed to state a mathematical model for satisfying the demand at Ikagami at minimum cost.

49 The local supermarket buys lettuce each day to ensure really fresh produce. Each morning, any lettuce that is left from the previous day is sold to a dealer that resells it to farmers who use it to feed their animals. This week, the supermarket can buy fresh lettuce for $7.00 a box. The lettuce is sold for $18.00 a box and the dealer that sells old lettuce is willing to pay $2.00 a box. Past history says that tomorrow's demand for lettuce averages 255 boxes with a standard deviation of 40 boxes.

Jennifer has a small business mixing and selling essential oils. One product is a mixture of two oils, lavender and peppermint. She asked her assistant, Carmen, to check on two suppliers to determine the costs for her next batch. Carmen contacted the suppliers and got quotes from each for the order. She misplaced the number of ounces of each oil she needed to purchase. The information she has is: Supplier A: lavender: $5.80$5.80/ounce peppermint: $4.20$4.20/ounce Total cost: $128.40$128.40 Supplier B: lavender: $4.50$4.50/ounce peppermint: $5.00$5.00/ounce Total cost: $124$124 She decides to solve a system of equations to determine the number of ounces of lavender, LL and of peppermint, PP, she should order. What system of equations can Jennifer use to find LL and PP?
22. A purchasing agent for a particular type of silicon wafer used in the production of semiconductors must decide among three sources. Source A will sell the silicon wafers for $2.50 per wafer, independently of the number of wafers ordered. Source B will sell the wafers for $2.40 each but will not consider an order for fewer than 3,000 wafers, and Source C will sell the wafers for $2.30 each but will not accept an order for fewer than 4,000 wafers. Assume an order setup cost of $100 and an annual requirement of 20,000 wafers. Assume a 20 percent annual interest rate for holding cost calculations. a. Which source should be used, and what is the size of the standing order? b. What is the optimal value of the holding and setup costs for wafers when the optimal source is used? c. If the replenishment lead time for wafers is three months, determine the reorder point based on the on-hand level of inventory of wafers.
