[Question]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?
[Answer]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: Jerry has an interesting novel he borrowed from a friend to read over the weekend. The book has 93 pages. On Saturday, he reads 30 pages. On Sunday, he goes to church and comes back, sits down, and reads 20 pages of the book. How many pages are remaining before Jerry can finish the book?
A: When Jerry reads 30 pages on Saturday, he would be remaining with 93 - 30 = 63 pages. After reading an additional 20 pages on Sunday, he would be remaining with 63 – 20 = 43 pages. The answer is 43.
Question: Gina can paint six cups an hour with roses and 7 cups an hour with lilies. Her Etsy store gets an order for 6 rose cups and 14 lily cups. If Gina gets paid $90 total for the order, how much does she make per hour?
Answer: First find the total time to paint the rose cups: 6 cups / 6 cups / hour = 1 hour. Then find the total time to paint the lily cups: 14 cups / 7 cups / hour = 2 hours. Then add the painting time for each type of cup to find the total painting time: 1 hour + 2 hours = 3 hours. Then divide Gina's total earnings by the number of hours she works to find her hourly wage: $90 / 3 hours = $30 / hour. The answer is 30.
[Question]There are 192 soaps in a package. They put them in 2 big boxes. If each box contains 6 packages, how much soap do the 2 boxes contain in total?
[Answer]Find how many soaps are in 1 box by multiplying the number of soaps per package by the number of packages per box: 192 * 6 = 1152 soaps. Then find how many soaps 2 boxes contain by multiplying the number of boxes by the number of soaps per box: 1152 * 2 = 2304 soaps. The answer is 2304.
Q: Leila and Mohamed decided to donate their old toys to a children’s home. Leila gave 2 bags with 25 toys in each bag. Mohamed’s donation was 3 bags with 19 toys in each bag. How many more toys did Mohamed donate?

Question: Grayson has 100 questions on a test. He answers some of the questions for 2 hours, taking two minutes for each answer, then realizes he doesn't know the rest of the questions. How many questions does Grayson leave unanswered when he submits his test?
Answer:
Each hour contains 60 minutes, so after 2 hours he took 2 * 60 = 120 minutes. If each question takes two minutes, then he answered 120 / 2 = 60 questions. Unanswered questions is 100 - 60 = 40 questions. The answer is 40.
