Cindy found a collection of baseball cards in her attic worth $8,000. the collection is estimated to increase in value by 1.5% per year. write an exponential growth function and find the value of the collection after 7 years

A]

Exponential function is given by the form:

y=a (b) ˣ

where:

a=initial value

b=growth factor

From the question:

a=$8000, b=1.015,

thus the exponential growth function of this situation is:

y=8000 (1.015) ˣ

b] The value of the collection after 7 years will be:

x=7 years

Using the formula:

y=8000 (1.015) ˣ

plugging the values we get:

y=8000 (1.015) ⁷

y=8,878.76

Answer: $8,878.76
