To determine the correct expression that represents how many boxes of kazoos Mr. Jackson needs to order, we need to find the total number of students and then divide that total by the number of kazoos in each box (which is given as 8).
-
First, we calculate the total number of students:
- Second graders: 26
- Third graders: 24
- Fourth graders: 30
Total number of students = 26 + 24 + 30 = 80
-
Next, we'll represent the total number of kazoos needed as 80. Since the kazoos come in boxes of 8, we divide the total number of students by the number of kazoos per box:
Number of boxes needed = Total number of students ÷ Number of kazoos per box = 80 ÷ 8
-
Therefore, the expression that represents the number of boxes Mr. Jackson needs to order is:
\[ (26 + 24 + 30) ÷ 8 \]
Now looking at the options provided:
- A: (26 x 24 x 30) + 8
- B: (26 + 24 + 30) x 8
- C: (26 + 24 + 30) ÷ 8
- D: (26 * 24 * 30) ÷ 8
The correct answer is C: \((26 + 24 + 30) ÷ 8\).
