Question: Modeling Consumer Price Index The consumer price index (CPI) is calculated by averaging the prices of various items after assigning a weight to each item, where the average for 1984 was 100.

(a) Find an equation that models these data.
(b) Use the model to predict the consumer price index in 2013.
(c) According to the model, during what year will the consumer price index pass 300?
