Question 1025531
The amount, or future value of the deposit is given by the formula

{{{A = P*(1+r/n)^(nt)}}}.

In this case, P = 450,000, r = 4.5% = 0.045, n = 4 (quarterly!), and t = 4.

==> {{{A = 450000*(1+0.045/4)^(4*4) = 538206.66}}}.

==>Interest earned is K538,206.66 - K450,000 = K88,206.66
