3.1. Outline the four main uses of inventory. 2 marks 3.2. A plant manager of a chemical plant must determine the lot size for a particular chemical that has a steady demand of 30 barrels per day. The production rate is 190 barrel per day, and annual demand is 10,500 barrels, setup cost is \( \$ 200 \), annual holding cost is \( \$ 0.21 \) per barrel and the plant operates 350 days per year. Calculate for the following. 3.2.1.Length of Time Needed to Deplete Maximum On-Hand Inventory 3.2.2. Total annual cost with optimal production unit 3.2.3.The cycle length, for the optimal production unit 3.2.4.The production time per lot 8 marks

(a) \( \frac{13}{12}-\left(\frac{3}{4}+\frac{2}{3}\right) \)

The result displayed was 6.34 E 27 for one computation. The result displayed was \( 7.1 \mathrm{E}-35 \) for another computation

10. Durante el mes de julio la demanda de camperas, a \( \$ 100.000 \) cada una, fue de 5.000 unidades y la oferta fue de 300.000 unidades.Se espera una reducciór de la demanda de un \( 20 \% \) mensual hasta octubre por fin de temporada inverna y un cambio en el precio de \( 10 \% \) mensual. Por ello la demanda del bien es elástica. a- Elaborar tabla, graficar y determinar la situación del mercado. b-Mencionar 3 bienes sustitutos y 3 bienes complementarios. c-Calcular la elasticidad.
