[Question]James buys 2 puzzles that are 2000 pieces each. He anticipates for these larger puzzles he can do 100 pieces every 10 minutes. So how long would it take to finish both puzzles?
[Answer]His speed means he can do 10 / 100 = .1 minute per piece. So he can finish 1 puzzle in 2000 * .1 = 200 minutes. So these two puzzles take 200 * 2 = 400 minutes. The answer is 400.
Q: Jack is on the phone with a scammer who says the IRS will arrest Jack if he doesn't send them the codes from 6 $500 Best Buy gift cards and 9 $200 Walmart gift cards. After sending the codes for 1 Best Buy gift card and 2 Walmart gift cards, Jack wises up and hangs up. How many dollars' worth of gift cards can he still return?
A: First find the number of Best Buy gift cards Jack needs to return: 6 cards - 1 cards = 5 cards. Then multiply that number by the cost per card to find the total refund Jack gets from Best Buy: 5 cards * $500 / card = $2500. Then find the number of Walmart gift cards Jack needs to return: 9 cards - 2 cards = 7 cards. Then multiply that number by the cost per card to find the total refund Jack gets from Walmart: 7 cards * $200 / card = $1400. Then add the two refunds to find his total refund amount: $2500 + $1400 = $3900. The answer is 3900.
