                               This graph shows the growth of  Starbucks Coffee  from the years 1987-1999 through an Exponent and Logistic Model.

I estimated the amount of Starbucks in the year 2000 and 2001 and got 3611.95 and 5061.14 for each. But, the actual amount of Starbucks in the years 2000 and 2001 was 3501 and 4709 each.
