Today's word problem comes from the Official SAT Practice Test 2012-2013
In a certain store, the regular price of a refrigerator is $600. How much money is saved by buying this refrigerator at 20 percent off the regular price rather than buying it on sale at 10 percent off the regular price with an additional discount of 10 percent off the sale price?
Comment if you know the answer! The correct answer will be posted in the comments tomorrow if no one gets it.
