a. Consumer Expenditure:

2010 : 10 × 10+5 × 18 1 × 10= 200

2011 : 15 × 8 3 × 30 2 5 220

2012 : 20 × 5+4 × 25+5 × 10 250

b. Percentage change in the amount the consumer paid from 2010 to 2011: 10%

220-200 200一一× 100

Percentage change in the amount the consumer paid from 2011 to 2012: 13.6%

250 220 220 --× 100

c. It is problematic to use your answers to part b as measure of inflation because both price and consumption are changing.

2010 : 10 × 10+5 × 18 1 × 10= 200

2011 : 15 × 10+3 × 18+2 × 10= 224

2012 : 20 × 10+4 × 18 5 × 10 322

Rate of inflation from 2010 to 2011: 12%

224-200 × 100= 12 200

Rate of inflation from 2011 to 2012: 43.7%

322- 224 224 13 7 100 45

e. Using 2011 as base year,

2010 : 10 × 8 5 × 30 1 × 5 235
