My daughter Kim teaches and notes that the average student uses 75 sheets of paper every week.
A) How many sheets will a student use in a 42-week school year?
B) How many sheets will a class of 26 students use in a week?
Not sure how to approach the problem. Do I first multiply 42x7 for A and 26x7 for B because there are 7 days in a week?
sheets=75sheets/week * 42 weeks/year
b) sheets=75sheets/student*week * 26students
how many grams would be required to prepare a 500 capsules of 7.5 mg each
Suppose x sheets from a 470 sheet ream of paper have been used. How many sheets are left?
To answer these questions, you need to consider the information given and apply appropriate calculations. Let's break them down step-by-step:
A) To find the number of sheets a student will use in a 42-week school year, you need to multiply the average number of sheets used per week (75) by the number of weeks in a school year (42).
Solution: Number of sheets used in a 42-week school year = 75 sheets/week × 42 weeks.
B) To find the number of sheets a class of 26 students will use in a week, you need to multiply the average number of sheets used per week (75) by the number of students in the class (26).
Solution: Number of sheets used by a class of 26 students in a week = 75 sheets/week × 26 students.
You do not need to multiply by 7 in either case, as the given information is already based on the average number of sheets used per week. If the question asked for the number of sheets used in a day, you would multiply by 7 since there are 7 days in a week.
Now, let's calculate the answers:
A) Number of sheets used in a 42-week school year = 75 sheets/week × 42 weeks = 3,150 sheets.
B) Number of sheets used by a class of 26 students in a week = 75 sheets/week × 26 students = 1,950 sheets.
Therefore, in a 42-week school year, a student would use 3,150 sheets of paper, and a class of 26 students would use 1,950 sheets of paper in a week.
