A）Firstly,we can suppose the number of each goods and services in a basket is one. Then we can get the total consumption of a typical family in the Base Year is $70*1+$50*1+$100*1+$200*1=$420
Secondly, suppose the same basket of goods and services that a typical famliy consumes in Year 1,then we can get the total consumption of the Year 1 is $100*1+$60*1+$90*1+$225*1=$475
Therefore, the change of CPI is ($475-$420)/$420=0.13095.That is to say CPI increased by 13% .
B) NO. Because we can acknowledge that the annual income of a typical family increase by （$210,000-$200.000)/$200.000=0.05. (5%)
