15. Annual sales for a surf shop are $130,000 and are increasing at a rate of 7% per year; 7 years
find the Function and the
Value after 7 years

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

Where P(t) is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

It's given the annual sales for a surf shop are Po=$130,000. They are increasing at a rate of r=7% = 0.07 per year. Substituting values, the function is:

The value of the function after t=7 years is

Computing:

not sure but it may be b, as i said i'm not sure.
