Question 173270
Rewriting w/o parenthesis:
{{{A=P(1+r/2)^2}}}
{{{A=P(1+r/2)(1+r/2)}}}
{{{A=P(1+r/2+r/2+r^2/4)}}}
{{{A=P(1+r+r^2/4)}}}
{{{A=P(r^2/4 + r + 1)}}}
{{{A=Pr^2/4 + Pr + P}}}
.
Evaluate when:P=$200 and r=10%
{{{A=Pr^2/4 + Pr + P}}}
{{{A=200(.10)^2/4 + 200(.10) + 200}}}
{{{A=50(.10)^2 + 20 + 200}}}
{{{A=50(0.01) + 20 + 200}}}
{{{A=0.5 + 20 + 200}}}
{{{A=220.5}}}
