The third competitor jumped two feet shorter than the third competitor, for a distance of 23 - 2 = 21 feet.

Q: Two puppies, two kittens, and three parakeets were for sale at the pet shop. The puppies were three times more expensive than the parakeets, and the parakeets were half as expensive as the kittens. If the cost of one parakeet was $10, what would it cost to purchase all of the pets for sale at the pet shop, in dollars?
A: Puppies cost three times more than parakeets, or 3 * $10 = $30 per puppy. Parakeets were half as expensive as the kittens, or 2 * $10 = $20 per kitten. Two puppies cost 2 * $30 = $60. Two kittens cost 2 * $20 = $40. And three parakeets cost 3 * $10 = $30. Thus, the cost to purchase all of the pets for sale at the pet shop is $60 + $40 + $30 = $130. The answer is 130.
Question: Stacy went to a store to buy some pairs of shorts. Each pair normally cost $10, but there's a discount of 10% on the total cost for people who purchase 3 or more pairs at once. How much can she save by buying 3 pairs at once as opposed to purchasing them individually at different times?
Answer:
Without the discount, each pair cost $10 so 3 pairs cost 3 * $10 = $30. With a discount of 10% on the total cost, she can pay only $30 - ($30 * (10 / 100)) = $27. By buying 3 at once in order to get the discount, she can save $30 - $27 = $3. The answer is 3.
