Calculating a Weighted Price Index Change
A simplified price index is calculated using a basket with only two goods: gasoline and bread. A typical household spends 15% of its budget on gasoline and 5% on bread. In one year, the price of gasoline increases by 40%, while the price of bread decreases by 10%. Assuming spending on all other goods remains unchanged, what is the total percentage contribution of gasoline and bread to the change in the overall price index? Show your calculation.
