Question

The sales at a particular bookstore grew from $2003 million in 2000 to $3871 million in 2005. Find an exponential function to model the sales as a function of years since 2000. Give your answer using the form B = B(o)*a^t.

Answer 1

B(o) is 2003 (in millions), I need the exact value of a. I have tried .131773 and 1.140849731 and neither one of them has worked.

Answer 2

Use excel to find your exponential function, it's the easiest way.
Make time your x value and money your y value in a table and create a scatter graph.
Right click on the points that have been graphed and add a trendline.

Answer 3

You can also tick a box that allows you to create an exponential equation.

Answer 4

you can use regression
