There are seventeen students in a class. Twice a year each student gets a new box of crayons. Boxes of crayons are packaged in groups of twelve. How many packages of twelve crayon boxes does the class need for a year?

3 Packages = 36 boxes, with (17*2) boxes needed for the year, means there are 2 boxes left for next year.

To find out how many packages of twelve crayon boxes the class needs for a year, we can follow these steps:

Step 1: Determine the total number of crayon boxes needed for one student for a year.
Since each student gets a new box of crayons twice a year, the total number of crayon boxes needed for one student for a year is 2.

Step 2: Calculate the total number of crayon boxes needed for all the students in the class.
We have 17 students in the class, so to find the total number of crayon boxes needed for the class, we need to multiply the number of crayon boxes needed for one student by the total number of students.
Total crayon boxes for the class = 2 * 17 = 34 crayon boxes.

Step 3: Determine the number of packages of twelve crayon boxes needed for the class.
Since crayon boxes are packaged in groups of twelve, we need to divide the total number of crayon boxes for the class by 12 to find out how many packages are needed.
Number of packages of twelve crayon boxes = 34 / 12 = 2.83 (rounded up to the nearest whole number)

Therefore, the class needs 3 packages of twelve crayon boxes for a year, with one box leftover.

To find out how many packages of twelve crayon boxes the class needs for a year, you need to determine the total number of crayon boxes required for all the students and then divide it by the capacity of each package.

Step 1: Find the total number of crayon boxes used by all the students in a year.
Since each student gets a new box of crayons twice a year, the total number of boxes for one year for all the students can be calculated by multiplying the number of students (17) by the number of times they get a new box of crayons in a year (2).
17 students * 2 boxes/year = 34 boxes/year.

Step 2: Determine the number of packages required to accommodate all the crayon boxes.
Since the boxes of crayons are packaged in groups of twelve, divide the total number of crayon boxes used in a year (34 boxes/year) by the capacity of each package (12 boxes/package).
34 boxes/year ÷ 12 boxes/package = 2.83 packages/year.

Since we can't have a fraction of a package, you would need to round up to the nearest whole number. Therefore, the class needs 3 packages of twelve crayon boxes for a year.
