A necklace was priced between $50 and $100 was on sale at 25% off. When the original price (a whole dollar amount) was discounted, the sale price was also a whole number of dollars. What are the possible original prices for the necklace?

    the possible answer would be 52,56,60,64,68,72,76,80,84,88,92,and 96.Basically any number that goes into 4 in between 50 and 100.

    I am trying to help my son with the same problem. At first I thought the above answer was correct too. Then I started to second guess myself because $50-$100 is the SALE price so we need to find the ORIGINAL price THEN take 25% off that to get the sale price. The above answer (52, 56, 60, 64....) is if we take 25% off of the sale price ($50-$100). I think we are doing it backwards. ????? I understand that it's every 4 numbers but I think it may be 68, 72, 76.....
    If we assume $68 is the original price and take 25% of $68, then we get a sale price of $51. Any thoughts? Again, I have no idea which way is correct.
