1.Suppose that the residents of Vegopia spend all of their income on cauliflower, broccoli and carrots. In 2017 they buy 100 heads of cauliflower for $ 200, 50 bunches of broccoli for $ 75 and 500 carrots for $ 50. In 2018 they buy 75 heads of cauliflower for $ 225, 80 bunches of broccoli for $ 120 and 500 carrots for $ 100. If the base year is 2017, what is the CPI in both years?
