Assume that the market basket of goods and services purchased in 2004 by the average family in the united states costs $14,000 in 2004 prices, whereas the same basket costs $21,000 in 2009 prices. however, the basket of goods and services actually purchased by the average family in 2009 costs $20,000 in 2009 prices, whereas this same basket would have cost $15,000 in 2004 prices. given this data, a laspeyres price index of 2009 prices using 2004 as the base year would be:
a) 1.05.
b) approximately 1.07.
c) approximately 1.33.
d) 1.50.
