Use the table below to answer the following questions). Shirley Templeton is a real estate agent for Paralol Realty. Shirley is given the responsibility to manage potential customers for 5 of the Realty's bungalows. These 5 bungalows are situated in close proximity. In order to make traveling easier, Shirley decides to move to a location closer to the 5 bungalows. The table below gives the location X and Y coordinates) of the 5 bungalows along with the number of trips she would have to make to each bungalow. Create a nonlinear model based on the data given in the table below noting that the objective is to reduce the weighted distance between Shirley's accommodation and the 5 bungalows. Bungalow Location data Locatim X-coardinate Y-coardinate Trips/Month Bungaldw 1 0 0 6 Bungaldw 2 25 100 30 Bungaldw 3 20 75 15 Bungaldw 4 90 80 28 Bungaldw 5 60 100 10 -According to the model, which of the following bungalows is Shirley's new accommodation closest to?

Stone Age Surfboards is a small manufacturer of two types of popular low-tide surfboards, the Graystone and the Lava models. The manufacturing process consists of two departments: fabrication and finishing. The fabrication department has 8 skilled workers, each of whom works 9.25 hours per day. The finishing department has 5 workers, each of whom works a 6-hour shift per day. Each pair of Graystone surfboards requires 2.5 labor hours in the fabrication department and 2 labor hours in finishing. The Lava model requires 4.2 labor-hours in fabrication and 3.6 labor-hours in finishing. The company operates 6 days a week. It makes a per unit profit of $40 on the Graystone model and $60 on the Lava model. The company anticipates selling at least twice as many Lava models as Graystone models. Use the spreadsheet below for Stone Age Surfboards to answer the following questions) using integer constraints on variables in the optimization models using the standard Solver. -What is the total profit generated?

LO1: Develop and solve nonlinear optimization models for different applications. Use the table below to answer the following questions). Pickson Luthiers Corporation is studying where to locate a phone charging point on the factory floor. The locations of five production cells are expressed as X- and Y-coordinates on a rectangular grid of the factory layout. The daily demand for the charging point measured as the number of trips to the charging point) at each production cell is also known. Because of the nature of the equipment layout in the factory and for safety reasons, workers must travel along marked horizontal and vertical aisles to access the charger. Thus, the distance from a cell to the charger is measured as rectilinear distance. The table below provides the relevant information. Pickson Luthiers Corporation Phone Recharging Points Data Cell X -coordinate Y -coordinate Demand Measurements 2 5 27 Paint 1 3 12 Electricals 4 2 25 Testing 3.5 5 5 Packnging 3 3 7 Maxirnum 4 5 The optimal location should minimize the total weighted distance between the charging point and all production cells, where the weights are the daily number of trips to the phone charging point. Create a nonsmooth optimization model, based on the data, to answer the following questions. Hint: Choose the closest answers.) -According to the model, which of the following is the weighted distance between the phone charger and Testing cell?
