Question

I have tried everything, but I do not know how to find the equation that expresses that specific change.

The number of passengers using a railway fell from 194379 to 173653 during a five year period. Find the annual percentage decrease over this period. Round your answer to 1 decimal place. Your answer is incorrect. Try again. Every exponential function has a constant relative (percent) rate of change. What is the equation that expresses that change? [Write the initial value as P0 and the base value as a.]

Explanation / Answer

Taking into account that the main datat is:

194379 to 173653 about the passangers, and the time is a period of 5 years, you could plot those values on Excel (office) as:

x = 0 , then y = 194379

x = 0, then y = 173653

, then select the points and make a exponential trend wich results as: 194379* (e-0.023x), where x will be the time.It has sense due the exponential is negative which represents the decrease.
