You open an investment account that earns a nominal interest rate of 4.2% a year. The current consumer price index is 108. In one year, the consumer price index is expected to go to 106. What is your expected real rate of return?

Consider the following basket of goods: 50 hamburgers, 10 textbooks, eight T-shirts, and 100 bottles of water. Suppose that in 2015, each hamburger was $3.50, each textbook was $89.99, each T-shirt was $14, and each bottle of water was $1.50. In 2016, each hamburger was $3.60, each textbook was $95, each T-shirt was $13, and each bottle of water was $1.65. What was the approximate value of the basket in 2015?
50(3.5) + 10(89.99) + 8(14) +100(1.50) = 1,337
