The purchasing power (real value of money) decreases if inflation is present in the economy. For example, the purchasing power of $34,000 after t years of 6% inflation is given by the model P = 34,000e 0.06t dollars. How long will it take for the value of a $34,000 pension to have a purchasing power of $17,000 under 6% inflation? It will take years. (Type an integer or a decimal rounded to two decimal places as needed.)
