(Carefully follow all numeric instructions. Enter your answer "as a percent, but without the percentage sign." In other words, if you think Bob predicts 99.99 percent inflation, just enter 99.99 in the blank.)

The purchasing power​ (real value of​ money) decreases if inflation is present in the economy. For​ example, the purchasing power of ​$33,000 after t years of 8​% inflation is given by the model P=33,000e−0.08t dollars. How long will it take for the value of a ​$33,000 pension to have a purchasing power of ​$16,500 under 8​% ​inflation?
