###Human: While buying DVDs at the store, Maria received a 25% discount. If the discount she received is $40, how much did she pay in total?, ### Assistant: Since 100 percent represent the original price, and she received a 25% discount which is $40, the original price is 100/25*40 = 160
Maria paid $160-$40 = $120 after receiving the twenty-five percent discount. 
 So the answer is :  120
