a) cost of basket: 2017 = $1,000.

2018 = $1,500.

2019 = $1,800.

"CPI2018 = 1500\/1000*100=150%." %.

"CPI2019 = 1800\/1000*100=180" %.

Inflation:

2018 = "(150-100)\/1000*100=50" %.

2019 = "(180-150)150*100=20" %.

b)The first difference is that the GDP deflator measures the prices of all goods and services produced, whereas the CPI or RPI measures the prices of only the goods and services bought by consumers. 

The second difference is that the GDP deflator includes only those goods produced domestically. 

The third difference concerns how the two measures aggregate the many prices in the economy. The CPI is computed using a fixed basket of goods, whereas the GDP deflator allows the basket of goods to change over time as the composition of GDP changes.
