3. Formulate the following decision problem using an appropriate technique, discuss the approach used and the findings. You would need to write 500(10%) words on this. This includes the calculations, assumptions, list of decision variables, list of constraints. The word limit applies for both of the tasks listed below. Case Study: An IT team intends to purchase at least 700 sensors, 700 transmitters and 5 gateway interfaces for the construction of a Wireless Sensory Network. The team pursued a tender process to secure its required raw materials from eligible suppliers. A final list of 8 eligible suppliers is put together, and the total cost of the materials that each supplier can supply are provided (please see Table 1). Table 1: List of Suboliers/Tender List 3.1)Formulate the decision problem and calculate the minimum cost (monetary unit) for purchasing at least 700 sensors, 5 gateways and 700 transmitters? 3.2.) Considering the high number of sensors and transmitters required for project, the team is asked to ensure that at least 4 suppliers are secured for supplying sensors, and at least 4 suppliers for transmitters. What would be the new minimum cost? Please note that a supplier can provide both sensors and transmitters
