Q: Jack is counting out his register at the end of his shift in the shop. His till has 2 $100 bills, 1 $50 bill, 5 $20 bills, 3 $10 bills, 7 $5 bills, 27 $1 bills, and a certain amount of change in coins. If he is supposed to leave $300 in notes as well as all the coins in the till and turn the rest in to the main office, how much money will he be handing in?
A: Jack's till has 2 * $100 + 1 * $50 + 5 * $20 + 3 * $10 + 7 * $5 + 27 * $1 bills, or $200 + $50 + $100 + $30 + $35 + $27 = $442. He's going to leave $300 in the till and turn the rest in to the office, so he'll be turning in $442 - $300 = $142. The answer is 142.
Question: John spent 3 years of his life exploring the jungle. He then spent half as much time writing up notes about his travels. It took .5 years to write his book once he was done with the notes. How long did he spend on his book and exploring?
Answer: He spent 3 * .5 = 1.5 years compiling notes. So it took him 3 + 1.5 + .5 = 5 years for everything. The answer is 5.
[Question]Tobias is a tractor salesman. His salary is based on the number of tractors he sells. For every red tractor he sells, he gets paid 10% of the sales price for each tractor. For every green tractor he sells, he gets paid 20% of the sales price for each tractor. This week, he sold 2 red tractors and 3 green tractors. The price of a single red tractor is $20,000. This week, Tobias's salary was $7000. What is the full price of a single green tractor, in dollars?
[Answer]For red tractors, 10% of the sales price is 10 / 100 * $20,000 = $2000. By selling two red tractors, he earned 2 * $2000 = $4000. Thus, of the $7000 salary he was paid this week, $7000 - $4000 = $3000 is from sales of green tractors. And since he sold three green tractors, the commission for the sale of a single green tractor is $3000 / 3 = $1000,. If $1000 is 20% of the full price, then the full price for a green tractor is (100 / 20) * $1000 = $5000. The answer is 5000.
Q: Bob is going to put in a vegetable garden on his property. It's going to be in one of the back corners of his land. He wants the width of the garden to be about an eighth of the width of his property, and the length to be a tenth of the length of his property. His land is 1000 feet wide and 2250 feet long. How many square feet is his garden going to be?
A: The width of his garden is going to be 1000 / 8 = 125 feet. The length of his garden is going to be 2250 / 10 = 225 feet. So the area of his garden is going to be 125 X 225 = 28125 square feet. The answer is 28125.
Question: Lauren wanted to make burgers and fries for dinner. She needed a few things from the grocery store and bought the following: 2 pounds of hamburger meat that was on sale for $3.50 a pound. 1 pack of hamburger buns for $1.50. A head of lettuce for $1.00 and a large 1.5-pound tomato that was priced at $2.00 per pound. She also needed a jar of pickles that cost $2.50 and she had a $1.00 off coupon for that item. How much change would Lauren get back if she paid with a $20 bill?
Answer: She bought 2 pounds of hamburger meat at $3.50 per pound so 2 * 3.50 = $7.00. The tomato weighed 1.5 pounds and cost $2.00 per pound so 1.5 * 2 = $3.00. When you add up all her items she spent 7 + 1.50 + 1 + 3 + 2.50 = $15.00. Her items added up to $15.00 and she had a $1.00 coupon off pickles so 15 - 1 = $14.00. She paid with a $20.00 bill so 20 - 14 = $6.00 in change. The answer is 6.
Q: If I'm 4 times older than Billy currently, and Billy is 4 years old, how old was I when Billy was born?
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

I would currently be 4 * 4 = 16 years old, since I'm 4 times older than Billy's age of 4. Therefore, in order to find my age at Billy's birth we'd simply subtract Billy's age of 4 from my age, meaning I was 16 - 4 = 12 years old. The answer is 12.
