Q: Eighteen hours ago, Beth and I took 100 photographs of our project. Today, Beth and I will take 20% fewer photographs of the same project. If we were to take 300 photographs of the project, how many photographs would we take to reach the target?
A: If you took 100 photographs of the project 18 hours ago, and today 20% few photographs have been taken, then 20 / 100 * 100 = 20 fewer photographs of the project have been taken today. The total number of photographs of the project that have been taken today is 100 - 20 = 80. So far, you've taken 80 + 100 = 180 photographs of the project. Since the target number of photographs is 300, the number of photographs that you need to take to reach the target is 300 - 180 = 120. The answer is 120.

Q: Mary does her grocery shopping on Saturday. She does her shopping only at a specific store where she is allowed a credit of $100, which must be paid in full before her next shopping trip. That week she spent the full credit limit and paid $15 of it on Tuesday and $23 of it on Thursday. How much credit will Mary need to pay before her next shopping trip?
A: So far, Mary has paid back $15 + $23 = $38 of the credit. So she still needs to pay $100 - $38 = $62. The answer is 62.
Question: While cultivating a small farm, a farmer spent $50 on corn seeds, $35 on fertilizers and pesticides, and $15 on labor. After a successful harvest, he was able to gather 10 bags of corn. How much should he sell each bag, if he wants to make a profit of 10%?
Answer: His total expenditure so far is $50 + $35 + $15 = $100. To make a profit of 10%, he has to make a total of $100 + ($100 * (10 / 100) = $110 from sales. To make $110 from the sales of 10 bags, each bag should cost $110 / 10 = $11. The answer is 11.
Q: Alice and Bob are each given $2000 to invest. Alice puts all of her money in the stock market and doubles her money. Bob invests in real estate and makes five times more money than he invested. How much more money does Bob have now than Alice?
A:
When Alice invested her money in the stock market, her money doubled to $2000 * 2 = $4000. Bob, after investing in real estate, increased his money by 2000 * 5 = 10000. The total amount of money that Bob made after investing in real estate is $10000 + $2000 = $12000. Bob made $12000 - $4000 = $8000 more than Alice after investing his money. The answer is 8000.
