Answer 1

use the formula

A = P*(1+r/n)^(n*t)

in this case,

P = 4280.83
r = 0.054
n = 2
t = 25

plug them into the formula to find the value of A. Tell me what you get.

Answer 2

A= 16219. 97

Answer 3

That's the total amount of money in the account after 25 years.

That money consists of the initial principal ($4,280.83) plus interest earned over the 25 years.

Let x be the amount of interest earned. So that means


P + I = A

4280.83+x = 16219. 97

x = ??

Answer 4

x= 11939.14
