Q: At a garage sale, Tish bought 4 items: a red horseshoe magnet, two stuffed animals, and a large sticker which read, "Why can't teachers solve their own math problems?" The magnet cost three times more than the sticker, but only one quarter the price of the two stuffed animals combined. If the Magnet cost $3, how much, in dollars, did a single stuffed animal cost?
A: If the magnet cost 3 - times more than the sticker, the sticker cost 3 / 1 = 1 dollar. If the magnet cost 1 / 4 the price of the two stuffed animals combined, then two stuffed animals cost 3 * 4 = 12 dollars. Thus, a single stuffed animal cost 12 / 2 = 6 dollars. The answer is 6.

Q: Jenny had $24 left after spending 3/7 of her money. How much is half of her original amount of money?
A: Jenny spent 1 - 3 / 7 = 4 / 7 of her money. Since 4 / 7 is equal to $24, then 1 / 7 is equal to $24 / 4 = $6. So, Jenny originally had $6 x 7 = $42. Therefore, half of her original amount of money is $42 / 2 = $21. The answer is 21.
