question:f Kim initially takes 4 classes in school, each lasting 2 hours, and then drops 1 class, how many hours of classes does she have per day now?
answer:Kim initially takes 4 classes, each lasting 2 hours, so she has a total of 4 * 2 = 8 hours of classes per day. After dropping 1 class, she now has 4 - 1 = 3 classes. Since each class still lasts 2 hours, she now has 3 * 2 = 6 hours of classes per day. 6 The answer is: 6
question:Alex is working on a science project and has taken pictures of all of the plants in a park near her home. She wants to find out how many of each plant she has pictures of, but she has x pictures, and counting them all will take her a long time. Her teacher suggested she use a program on the computer that can automatically tell her what plant is in each picture and count them for her. It will take the program 2 minutes to process each picture. It will take 32 hours to process all of the pictures. What is the value of unknown variable x?
answer:To solve this problem, we need to determine the value of x, which represents the number of pictures Alex has taken. We know that it takes 2 minutes to process each picture. Let's find out how many minutes it will take to process all the pictures: 32 hours = 32 * 60 = 1920 minutes 2 minutes per picture * x pictures = 1920 minutes Let's solve for x: 2x = 1920 To isolate x, we divide both sides of the equation by 2: 2x / 2 = 1920 / 2 x = 960 The value of x is 960. Alex has taken 960 pictures. 960 The answer is: 960
question:f Annie has 70 left after purchasing 8 hamburgers for 4 each and 6 milkshakes for 5 each, what was the initial amount of money that Annie had, in dollars?
answer:Annie spent 8 hamburgers x 4 = <<8*4=32>>32 on hamburgers. She also spent 6 milkshakes x 5 = <<6*5=30>>30 on milkshakes. In total, Annie spent 32 + 30 = <<32+30=62>>62 on hamburgers and milkshakes. If Annie has 70 left after her purchases, then her initial amount of money was 70 + 62 = <<70+62=132>>132. 132 The answer is: 132
question:f Martha receives a daily allowance of 12 and decides to save half of this amount every day, except for one day when she saved only a quarter of this amount, how much has she saved at the end of the week?
answer:Martha receives a daily allowance of 12. She decides to save half of this amount every day, so she saves 12/2 = 6 every day, except for one day. On that one day, she saves only a quarter of her daily allowance, so she saves 12/4 = 3. In total, she saves 6 x 6 days + 3 = 36 + 3 = 39 at the end of the week. 39 The answer is: 39
