Question: 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?
Answer: 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.
[Question]Bess and Holly are playing Frisbee at the park. Bess can throw the Frisbee as far as 20 meters and she does this 4 times. Holly can only throw the Frisbee as far as 8 meters and she does this 5 times. Each time Bess throws a Frisbee, she throws it back to her original position. Holly leaves her Frisbee where it lands every time she throws it. In total, how many meters have the thrown Frisbees traveled?
[Answer]Bess throws the Frisbee out 4 times * 20 meters each time = 80 meters. She then throws it back which doubles the distance traveled to 80 meters * 2 = 160 meters. Holly throws the Frisbee out 5 times * 8 meters = 40 meters. So in total, Holly and Bess have thrown the Frisbees 160 + 40 = 200 meters. The answer is 200.
Q: Maci is planning for the new school year and goes to the store to buy pens. She needs ten blue pens and 15 red pens. If a blue pen costs ten cents each and a red pen costs twice as much as the blue pen, how much money does Maci pay for the pens?
A: Maci pays 10 * $0.10 = $1 for the blue pens. Each red pen costs 2 * $0.10 = $0.20. She pays 15 * $0.20 = $3.00 for the red pens. To buy all the pens she needs, Maci pays $3 + $1 = $4. The answer is 4.
