Question: John decides to trade in his stereo system. His old system cost 250 dollars and he got 80% of the value for it. He then buys a system that costs $600 that he gets a 25% discount on. How much money came out of his pocket?
Answer: He got 250 * .8 = $200. He gets a 600 * .25 = $150 discount on the second system. So it cost 600 - 150 = $450. So he was 450 - 200 = $250 out of pocket. The answer is 250.
[Question]Jenson and Kingsley have a tailoring business. Jenson makes 3 shirts, and Kingsley makes 5 pairs of pants per day. If each shirt uses 2 yards of fabric and a pair of pants uses 5 yards of fabric, how many yards of fabric do they need every 3 days?
[Answer]Jenson uses 2 x 3 = 6 yards of fabric for making shirts every day. Kingsley uses 5 x 5 = 25 yards of fabric every day for making pair of pants. So, the total yards of fabric they use per day is 25 + 6 = 31. Therefore, the total yards of fabric they use every 3 days is 31 x 3 = 93. The answer is 93.
Q: This year the Oscar swag bags include two diamond earrings that cost $6,000 each, a new iPhone that costs $2,000, and some designer scarves that each cost $1,500. If the total value of the swag bag is $20,000, how many scarves are there?
A: First find the total cost of the diamond earrings: $6,000 / earring * 2 earrings = $12,000. Then subtract the cost of the earrings and iPhone from the total cost of the bags to find the cost of all the scarves: $20,000 - $12,000 - $2,000 = $6,000. Then divide the total cost of the scarves by the cost per scarf to find the number of scarves: $6,000 / $1,500 / scarf = 4 scarves. The answer is 4.
