A small nation idolizes the TV show The Voice. All they produce and consume are karaoke machines and CDs, in the following amounts:

Karaoke Machines CDs Quantity Price Quantity Price 2020 10 $40 30 $10 2021 12 60 50 12

a. Using a method similar to the CPI, compute the percentage change in the overall price level.
Use 2020 as the base year and fix the basket at 1 karaoke machine and 3 CDs.

b. Using a method similar to the GDP deflator, compute the percentage change in the overall price level. Again, use 2020 as the base year.

c. Is the inflation rate in 2021 the same using the two methods? Explain why or why not.
