Explanation of Solution

The change in price is calculated below:

  PriceIndex=BasketPriceBasketPriceinbaseyear×100=$800$2,000×100=40

  InflationRate= CPI x+1 CPIx CPIx=238100100×100=138%

The response does not appear to be correct, because it suggests that the basket price increases when CPI increases. For example, in some cases like the scenario above the basket price may decrease. This is due to advances in technology.
