Which is the best for money €800 table with 50% off or €600 table with 30% off

50% would be turned into a decimal so. 5

next you would multiply it by 800 so 800*.5=400

then you subtract 800-400=400

Then you do the same thing with the other side

30% =.3

600*.3=180

600-180=420

So $800 with 50% would be a better deal
