Question

Mrs. Rushing has 3 chemistry classes with 24 students in each. An experiment calls for each student to use 4 test tubes.

How many test tubes are needed in all for her classes?

Answer 1

3*24 for each class, * 4 for each student= 288

Answer 2

288 test tubes

Step-by-step explanation:

Given,

Total chemistry classes = 3

The number of students in each classes = 24,

So, the total number of students in 3 classes = 3 × 24 = 72,

Also, each student to use 4 test tubes.

Therefore, the number of test tubes in 3 classes = 4 × 72 = 288,

Hence, 288 test tubes are needed in all for her classes.
