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 expenditure on each item in the market basket and the total dollar expenditure on market 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 Quantity in Market Basket (Dollars) Expenditure (Dollars) Notebooks 10 2 20 Price (Dollars) 1 Expenditure (Dollars) (Dollars) 3 Price Expenditure (Dollars) 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 2017. In the last row of the table, calculate and enter the value of the CSPI for the remaining years. Between 2017 and 2018, the CSPI increased by Between 2018 and 2019, the CSPI increased by
