Under the chain rule, we compare the GDP of each two consecutive years in terms of prices that prevail in the earlier year. For example, to compare 2017 and 2018, we must first calculate GDP in both years in 2017 prices. Consider an economy that produces only two goods, bread and cheese. The following statistics are available about this economy. In the following questions, round your answers to two decimal places.

2017: Base Year 2018 2019

Quantity Price Quantity Price Quantity Price

Bread 40 1 50 2 50 1

Cheese 30 2 26 2 30 4
