Question: Elizabeth wants to buy the steak knives from a bridal registry as a wedding gift. The couple registered for 2 steak knife sets and each set contains 4 steak knives. If Elizabeth buys both sets and they cost $80.00 per set, how much does each single steak knife cost?
Answer: Each steak knife set has 4 steak knives and Elizabeth bought 2 sets so there are 4 * 2 = 8 steak knives in total. Each steak knife set costs $80.00 and she bought 2 sets so she spent $80 * 2 = $160.00. Both sets cost $160.00 and there are 8 knives in total so each knife costs 160 / 8 = $20.00 each. The answer is 20.
[Question]Tom needs to buy a new gaming system. He trades in his super Nintendo for an original NES. The SNES is worth $150 and the store gives him 80% of that value. He gives $80 and gets back $10 change and a game worth $30. How much was the NES on sale for?
[Answer]He traded in the SNES for 150 * .8 = $120. Including the money he gave, he spent 120 + 80 = $200. He got 10 + 30 = $40 in change. So the NES cost 200 - 40 = $160. The answer is 160.
Q: In a restaurant, one cup of coffee is $6 and a piece of cheesecake $10. When buying them together, the client gets a 25% discount. What is the final price of such a set?
A: Both the cheesecake and coffee cost 10 + 6 = $16. The discount for these items is 25 / 100 * 16 = $4. So the final price for the cheesecake and coffee is 16 - 4 = $12. The answer is 12.
Question: Chastity made 12 angel food cakes to give to friends. She placed the cakes in boxes, and then walked them out to her car. But she had forgotten her keys. So, she placed the boxes of cakes in one stack on the hood of her car, and then she ran back into the house to get her keys. But before she returned, a black crow came, landed on the stack of cakes, and knocked over half of the stack. When Chastity returned, she picked up half of the fallen cakes, which were not damaged, but the rest of the cakes were destroyed. How many cakes were destroyed?
Answer: There were 12 / 2 = 6 fallen cakes. Half of 6 fallen cakes were destroyed, for a total of 6 / 2 = 3 cakes. The answer is 3.
[Question]Ernest bought 50 meters of wire and cut it into 5 equal parts. He then used 3 parts of the wire. How many meters of wire is not used?
[Answer]Each part of the wire is 50 / 5 = 10 meters long. Ernest used 3 parts, then he used 10 x 3 = 30 meters of the wire. Therefore, 50 - 30 = 20 meters of wire is not used. The answer is 20.
[Question]10 boxes each contain 50 bottles of water. Each bottle has a capacity of 12 liters and is filled up to 3/4 of its capacity. How many liters of water altogether are contained within the bottles in the boxes?
[Answer]
Since each water bottle has a capacity of 12 liters, when filled up to 3 / 4 of capacity, each carries 3 / 4 * 12 = 9 liters of water. If there are 50 bottles of water in each box, the number of liters the water bottles in a box are carrying is 50 * 9 = 450 liters. In 10 boxes containing bottled water, the total number of liters in the water bottles is 450 * 10 = 4500 liters. The answer is 4500.
