Liquid levies escalate by 20% while usage contracts by 20%. Consequently, compute the percentage shift in financial expenditure:________?
Show answer Hide answer
Answer: D. 4 % decrease
Explanation
A twenty percent price increase multiplies the original expenditure baseline by one point two. A twenty percent usage reduction multiplies the adjusted figure by zero point eight. Multiplying one point two by zero point eight yields zero point nine six, showing a decrease. Successive percentage changes are applied multiplicatively rather than through simple addition. A multiplier below one represents a net reduction from the initial baseline value. Financial expenditure is the product of unit price and total quantity consumed.
Economic forecasting models use successive percentage adjustments to analyze inflation and consumption shifts. Business budgeting requires understanding how offsetting price and demand changes impact overall revenue. Consumer spending patterns fluctuate based on combined pricing and utility consumption trends. Option A is incorrect because simultaneous opposing percentage changes do not cancel each other out. Option B incorrectly calculates the magnitude of the percentage reduction in expenditure. Option C incorrectly assumes an increase instead of a decrease in financial expenditure.
