Question: Steve writes a letter every 3rd day to his friend. He spends 20 minutes writing the letters. It takes 10 minutes to write 1 page. He also writes a long letter at the end of the month which he puts more thought into. It takes twice as long per page but he spends 80 minutes writing. How many pages does he write a month?
Answer: He writes 30 / 3 = 10 normal letters. Each letter is 20 / 10 = 2 pages. So that is 2 * 10 = 20 pages. His long letter takes 2 * 10 = 20 minutes per page. So it is 80 / 20 = 4 pages. So he writes 20 + 4 = 24 pages. The answer is 24.

Q: Alice's white water rafting class is composed of 40 students and 10 instructors, including herself. She has 20 life vests on hand. 20% of her students are bringing life vests. How many more life vests will Alice need to get so that entire class has one?
A: 20% of her 40 students will bring their own life vest so .20 * 40 = 8 students will bring their life vests. Alice has 20 life vests and 8 students will bring there's so that's 20 + 8 = 28 life vests. There are 40 students and 10 instructors total so that's 40 + 10 = 50 people in the class. If there are 28 life vests and she has 50 people then she needs to find 50 - 28 = 22 more life vests. The answer is 22.

[Question]Brendan makes $6/hour as a waiter. He's scheduled for 2 8-hour shifts and 1 12-hour shift this week. He also makes an average of $12 in tips each hour. Brendan is supposed to pay 20% of his income in taxes, but he only reports 1/3rd of his tips to the IRS. How much money does Brendan pay in taxes each week?
[Answer]First find the total number of hours Brendan works for the 8 - hour shifts: 2 shifts * 8 hours / shift = 16 hours. Then find the total number of hours Brendan works by adding those hours to the 12 - hour shift: 16 hours + 12 hours = 28 hours. Now find Brendan's total wage earnings by multiplying his $6 / hour wage by the number of hours he works: $6 / hour * 28 hours = $168 / week. Now figure out how much Brendan makes in tips by multiplying the number of hours he works by the amount of tips he makes per hour: $12 / hour * 28 hours / week = $336 / week. Now divide that number by 3, since Brendan only reports a third of his tips: $336 / week / 3 = $112 / week. Now add Brendan's wage earnings to that number to find how much income he reports to the IRS each week: $168 / week + $112 / week = $280 / week. Finally, multiply Brendan's reported income by his tax rate to find how much he pays in taxes each week: $280 / week * .2 = $56 / week. The answer is 56.
[Question]Stella’s antique shop has 3 dolls, 2 clocks and 5 glasses for sale. She sells the dolls for $5 each. The clocks are priced at $15 each. The glasses are priced at $4 each. If she spent $40 to buy everything and she sells all of her merchandise, how much profit will she make?
