Hello, please help me with this I continue to get it incorrect.

6 . 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 2 20 3 Calculators 50 50 54 75 Large coffees 200 1 200 1 1 Energy drinks 100 200 A 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 9% . Between 2018 and 2019, the CSPI increased by % Which of the following, if true, would illustrate why price indexes such as the CSPI might overstate inflation in the cost of going to college? Check all that apply. As the price of textbooks increased, more and more students turned to the used-book market or chose not to buy textbooks at all, instead using the copies on reserve in the library. O Professors required each student to buy 10 notebooks, regardless of the price. A new, safe method of memory enhancement became available for purchase. O The quality and design of calculators improved dramatically from 2017 to 2019. For example, calculators made in 2019 accept memory cards, whereas those made in 2017 do not, but this quality change is hard to measure
