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 2019, 2020, and 2021. The expenditure on each item in the market basket and the total dollar expenditure on market basket are shown for 2019. Perform these same calculations for 2020 and 2021, and enter the results in the following table. 2019 2020 2021 Price Expenditure Price Expenditure Price Expenditure Quantity in Market Basket (Dollars) (Dollars) (Dollars) (Dollars) (Dollars) (Dollars) Notebooks 10 2 20 1 3 Calculators 1 50 50 54 75 Large coffees 200 1 200 1 1 Energy drinks 100 2 200 3 4 Textbooks 10 100 1,000 120 150 Total cost 1,470 Price index 100 Suppose the base year for this price index is 2019. In the last row of the table, calculate and enter the value of the CSPI for the remaining years. Between 2019 and 2020, the CSPI increased by % Between 2020 and 2021, the CSPI increased by %
