You go to Red Lobster's to eat and spend $125 and the waitress was great and you want to leave her a nice tip.  The general tip is 15% you want to leave a 20% tip ?  Well 625 because then you have that then you have to divide it and mutiple it 1258.20=1.25 then move the decimal.

25 is the anwser cuz you have to divide 125 by 15
