There are 50 staplers in the stapler. Stacie staples 3 dozen reports on her desk. How many staplers are left in the stapler?
Let's think: Stacie staples 3 x 12 = 36 reports. There are 50 - 36 = 14 staplers left in the stapler.. The answer is: 14.

Jean is trying to motivate herself to write her final paper. She eats one donut per 2 pages that she writes. If she writes 12 pages and each donut has 150 calories, how many calories does she eat?
Let's think: First find the total number of donuts Jean eats: 12 pages / 2 pages / donut = 6 donuts. Then multiply that number by the number of calories per donut to find the total number of calories she eats: 6 donuts * 150 calories / donut = 900 calories.. The answer is: 900.

The school is having a book-a-thon. The winning class gets a pizza party. The fifth grade has 20 students and one week to read as much as possible. The 6th grade already finished and read a total of 299 hours. How many hours does each student in 5th grade need to average per day to beat them by 1?
Let's think: The class needs to read 300 hours in a week because 299 + 1 = 300. The class needs to read 60 hours a day because 300 / 5 = 60. Each student needs to read 3 hours a day because 60 / 20 = 3.. The answer is: 3.

240 sixth-grade students were asked about the number of novels they read per month. 1/6 of students read three or more novels, 35% of students read two novels, 5/12 of students read one novel, and the rest of the students do not read anything. Calculate the number of students who do not read novels.
Let's think:
1 / 6 * 240 students = 40 students. So 40 students read three or more novels. 35 / 100 * 240 students = 84 students. So 84 students read two novels. 5 / 12 * 240 students = 100 students. So 100 students read a novel. 240 students (40 students + 84 students + 100 students) = 240 students 224 students = 16 students. So 16 students don't read novels.. The answer is: 16.
