Principal Amount = P = $250

Interest Rate = r = 9% = 0.09

Time in years = t = 15 years

Value of investment = A = ?

The formula to calculate the value on investment as a result of annual interest is:

[tex] A=P(1+r)^{t} [/tex]

Using the values in the above formula, we get:

[tex] A=250(1+0.09)^{15}\\ \\
A=\$ 910.62 [/tex]

Thus, at the end of 15 years the value of the investment will be $ 910.62.
