Question 1200570
To solve for this "x", the actual cost of the purchase for this TV is needed but is missing in the description.


The coupon and the in-store announcement are two separate things for this same TV.


The cost of purchase, without dealing with tax, is c, and if x is original price, then  {{{c=x-(0.25)x-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.
