Question 1197675
Normal Distribution: µ = 80,000 and σ =24,000  
{{{drawing(400,200,-5,5,-.5,1.5, graph(400,200,-5,5,-.5,1.5, exp(-x^2/2)), green(line(1,0,1,exp(-1^2/2)),line(-1,0,-1,exp(-1^2/2))),green(line(2,0,2,exp(-2^2/2)),line(-2,0,-2,exp(-2^2/2))),green(line(3,0,3,exp(-3^2/2)),line(-3,0,-3,exp(-3^2/2))),green(line( 0,0, 0,exp(0^2/2))),locate(4.8,-.01,z),locate(4.8,.2,z))}}}

A Percentage is the area under the Standard Normal Curve 
to the <font color = red><font size = 3><b>left of the z-score.</font></font></b>
  For example z = 2.0537  (when 2% is to the right & 98% is to the left)
 Calculator function: Invnorm(.98) = z = 2.0537 rounded
  amount = 2.0537*(24000) + 80,000 =  $129,289 (nearest dollar)

Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
is the key to Your Success working with the various Distributions.
