Question: 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?
Answer with step-by-step thinking: 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.
So the answer is 3900.

Question: Preston has a sandwich shop. He charges $5 for each sandwich. He also charges $20 for a delivery fee. Abra Company orders 18 sandwiches from Preston and also tips him 10%. How much total, in dollars, did Preston receive?
