Question

Amanda wants to buy a ruler for each student in the middle school. There are 338 ​fifth-graders, 326 ​sixth-graders, 451 ​seventh-graders, and 400 ​eighth-graders. Each box of rulers holds 18 rulers. How many boxes of rulers will Amanda need to​ buy?

Answer 1

Amanda will need to buy 85 boxes of rulers.

Step-by-step explanation:

To calculate the number of boxes of rulers Amanda needs to buy, we need to sum up the number of students in each grade level. There are 338 fifth-graders, 326 sixth-graders, 451 seventh-graders, and 400 eighth-graders.

We can add these numbers together to get the total number of students in the middle school:

338 + 326 + 451 + 400 = 1515

Since each box holds 18 rulers, we can divide the total number of students by 18 to find how many boxes Amanda will need to buy:

1515 ÷ 18 ≈ 84.2

Since we cannot have a fraction of a box, Amanda will need to buy 85 boxes of rulers.
