University authority has assigned you to build a model to analyze the total number of books that the
students of university want to buy from the university Bookshop. Discuss how vou are going to build a model in this
case. Discuss how we can use and apply the model you have just built.
According to economists, If the price of energy (oll and gas, increases, then the price or certain goods anc
services can also increase. Use the Model of Demand and Supply (diagram) to explain why this might be
the case. You can discuss using the example or any product
