<h3>Determining interest after 10 years </h3>
Interest = future value - amount deposited 
$3000 (1.015)^10 = $3,481.62
Interest =  $3,481.62 - $3000 = $481.62 
 
<h3>Determining the future value of the account.</h3>
  Future value of the lump sum = $3000 x (1.015)^11 = $3,533.85
Future value of the annuity = amount deposited x annuity factor 
Annuity factor = {[(1+r)^n] - 1} / r = [(1.015)^10 - 1] / 0.015 = 10.702722
Future value =  10.702722 x $1,200 = $12,843.27
Total future value =  $12,843.27 + $3,533.85 = $16,377.12
