Question

The sales at a particular bookstore grew from $2006 million in 2000 to $3803 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 = Boat

Answer 1

\[B=B_oa^t\] need to find "a"

Answer 2

B_o = 2000 (initial value). when t=5 (year 2005), you get the equation 3803=2000a^5. Solve for a by dividing by 2000 and taking the fifth root of each side.
