Demand for electrical services in your area is $12 million per year. It is expected to grow 10% compounded annually
over the next 5 years. What will demand be in 5 years? The formula for compound growth is E-Bx (1 + R)', where E is ending value, B is
beginning value, R is rate of growth, and T is the amount of time.

Answer:

  $19.3 million

Step-by-step explanation:

The demand in 5 years can be found by using the given formula for exponential growth with the given beginning value, growth rate, and time.

  E = B(1 +r)^t

You are given B = 12, r = 0.10, t = 5, so the ending value is ...

  E = 12(1 +0.10)^5 = 12(1.61051) = 19.32612

Demand for electrical services in 5 years will be about $19.3 million per year.
