Question 190007
<font face="Tahoma" size=1.5>
</pre><font size=4><b>
Let <font color=blue>$ x</font> = Original Price


It follows,
{{{x-0.20(x)=12590}}}, 20% off the Original Price


{{{x(1-0.20)=12590}}}
{{{x(0.80)=12590}}} ---> {{{cross(0.80)x/cross(0.80)=cross(12590)15737.50/cross(0.80)}}}
<font color=blue>x = $ 15,737.50 </font>(Original Price)


Thank you,
