Question: During the hot dog eating contest, the 1st competitor ate 12 hot dogs in 3 minutes. The 2nd competitor ate twice that amount and the 3rd competitor ate 25% less than the 2nd competitor. How many hotdogs did the 3rd competitor eat?
Answer: The 2nd competitor ate twice the amount of the 1st competitor's 12 hot dogs So he ate 2 * 12 = 24 hot dogs. The 3rd competitor ate 25% less than the 2nd's 24 hot dogs, which is 24 / 4 = 6 hot dogs. If the 2nd competitor ate 24 hot dogs, and the 3rd ate 25% less than that, then the 3rd competitor ate 24 - 6 = 18 hot dogs. The answer is 18.
[Question]Louise is in a toy store. She already has 28 toys worth $10 each in her cart. On her way to the till she adds 20 teddy bears to the cart. If the $580 in Louise’s wallet is exactly enough to pay for all the toys, how much does each teddy bear cost?
[Answer]Initially, Louise's cart has toys worth 10 * 28 = 280 dollars. If Louise pays for the toys originally in her cart, her wallet will remain with 580 - 280 = 300 dollars. Dividing the remaining amount by the number of teddy bears gives 300 / 20 = 15 dollars. The answer is 15.
