Answer:
The number of shops predicted in 2015 is 2,697.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of Starbucks shops in 1982 = 5
Growth annual rate of shops = 21% = 0.21
Number of years = 2015 - 1982 = 33
2. Find an equation for this growth and find the number of Starbucks predicted in 2015.
This is the formula we will use:
S = I * (1 + r) ^ t, where:
S = Number of shops in 2015
I = Initial number of shops in 1982
r = Growth annual rate of shops
t = Number of years since 1982
Replacing with the values we know:
S = 5 * (1 + 0.21) ^ 33
S = 5 * 1.21 ^ 33
S = 5 * 539.4
S = 2,697
The number of shops predicted in 2015 is 2,697.
