.
<pre>

(A)  Future value = {{{4000*(1+0.06)^3}}} = {{{4000*1.06^3}}} = 4764.06 dollars.


(B)  Interest in three years = 4764.06-4000 = 764.06  dollars.

---------------


If &nbsp;(C) &nbsp;is self-standing separate problem, &nbsp;then why do you post two separate problems in this post ?



The rule of this forum is 


<H3>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ONE and ONLY ONE problem per post.</H3>

Those who violate this rule, &nbsp;work against their own interests.
