To solve for this \"x\", the actual cost of the purchase for this TV is needed but is missing in the description.\r

\n" ); document.write( "\n" ); document.write( "The coupon and the in-store announcement are two separate things for this same TV.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The cost of purchase, without dealing with tax, is c, and if x is original price, then $\"c=x-%280.25%29x-100\"$ . Reason for this way is because the 25% off applies to everybody; but some customers might not have the coupon for the $100 off. \n" ); document.write( "
