The CPI consists of a bundle of commonly purchased goods and services.
The prices for these goods last year were $2.5, $7.00, $1.50, $12.00, respectively. The Laspeyres index, in which the quantities are from the base period, indicates how much an individual's income would have to increase to offset price increases so that the basket's utility remains the same.
