The following table shows how the buying power of a dollar is reduced with inflation. The second line in the table gives the percent reduction of a dollar's buying power in one year due to the corresponding inflation rate. Annual inflation rate 10% 20% 30% 40% 50% Buying power reduction 9.1% 16.7% 23.1% 28.6% 33.3% Annual inflation rate 60% 70% 80% 90% 100% Buying power reduction 37.5% 41.2% 44.4% 47.4% 50.0% If the buying power of a dollar declined by 27% during a year, what was the inflation rate during that year? Suggestion: First note that 27% is between 23.1% and 28.6%, so the answer must be an inflation rate between 30% and 40%. Interpolate to find the answer more accurately. (Round your answer to one decimal place.) x %
