Question 947345
Maybe the description is wrong.


COMPUTER AND PRINTER,  $2050.
PRINTER,  25% of the purchase cost of $2050:   {{{(25/100)(2050)=(1/4)(2050)=(1/2)(1025)=512.5}}}.
JUST the computer:   {{{ENTIREPURCHASE-PRINTER}}},     {{{2050-512.5=1537.5}}}



I cannot reproduce what you are expecting.


Recheck your problem description and question, very carefully.  One of us is missing something very simple.
