Jquery: Select two equal numbers on two different places and then apply css background yellow
<p>i have a table, inside of it here is a tr that has a td which contains "4a.Contrata". That same tr has a td with a price like "$125.45" and that price is the same number as ANOTHER td that is inside the table. 
What i want to do is add a css background yellow to those equal two prices. </p>

<p>Right now all im doing is adding a yellow background to the tr where "4a.contrata" is.</p>

<p>Here is the html of the description i made before, basically im trying to add yellow background to $162,87 (this number varies so i need to "select" this) both the price that is inside the table and the one that is right next to "4a.Contrata"</p>

<p>The price will change not only the number but the position. The logic i need toe express is: If a td is the same as the td that is inside the tr that contains 4a.Contrata then apply yellow background</p>
