1. Calculating inflation using a simple price index Consider a fictional price index, the College Student Price Index (CSPI), based on a typical college student's annual purchases. Suppose the following table shows information on the market basket for the CSPI and the prices of each of the goods in 2017, 2018, and 2019. The cost of each item in the basket and the total cost of the basket are shown for 2017. Perform these same calculations for 2018 and 2019, and enter the results in the following table. 2017 2018 2019 Price Cost Price Cost Price Cost Quantity in Basket (Dollars) (Dollars) (Dollars) (Dollars) (Dollars) (Dollars) Notebooks 10 5 50 7. 11 Calculators 1 100 100 110 140 Large coffees 150 150 Energy drinks 50 2 100 3 4 Textbooks 10 100 1,000 120 150 Total cost 1,400 Price index 100 Suppose the base year for this price index is 2017.
