Question 161712
<pre><font size = 4 color = "indigo"><b>
{{{A = P*(1+r/n)^(n*t)}}}

where A = final amount = 6600
      P = beginning amount (unknown)
      r = rate expressed as a decimal = 0.06
      n = number of compoundings per year = 4 (quarterly)
      t = number of years = 4

{{{6600 = P*(1+0.06/4)^(4*4)}}}

{{{6600 = P*(1+0.015)^(16)}}}

{{{6600 = P*(1.015)^(16)}}}

{{{6600 = P*1.268985548}}}

{{{6600/1.268985548=P}}}

{{{5201.00486=P}}}

So the nearest answed is c.
