Question 292600: Henry invested $12,000 in a new
restaurant. When the restaurant was sold two years
later, he received $27,000. Find his average annual
return by solving the equation 12,000(1 r)2
27,000.
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
F = P * (1+i)^n
F = 27000
P = 12000
i = what you want to find.
n = 2 years
Plug your values into this equation to get:
27000 = 12000 *
Divide both sides of this equation by 12000 to get:
=
Simplify to get:
2.25 =
Take the square root of both sides of this equation to get:
= 1+i
Simplify to get:
1.5 = 1+i
Subtract 1 from both aides of the equation to get:
i = .5
That's a 50% growth rate per year.
Plug that value into your original equation to get:
27000 = 12000 * becomes:
27000 = 12000 * which becomes:
27000 = 12000 * 2.25 which becomes:
27000 = 27000 confirming that the value of .5 interest rate of growth per year is accurate.
Your answer is that his average annual rate of return is 50%.
