5. In 1982, the number of Starbucks was 5 shops. It has exponentially grown by 21% yearly. Lett-the
number of years since 1982. Find an equation for this growth and find the number of Starbucks
predicted in 2015.

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.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
