Final answer:
To find the total number of glue sticks given to the classes, multiply the number of glue sticks given to each class by the total number of classes, which gives the answer 4,950 glue sticks.
Step-by-step explanation:
To find out how many glue sticks were given to the classes in all, we can multiply the number of glue sticks given to each class by the total number of classes. In this case, each class was given 225 glue sticks and there are 22 classes. So, we can calculate the total number of glue sticks given to the classes by multiplying 225 by 22:
225 x 22 = 4,950 glue sticks
Therefore, the correct answer is B. 4,950 glue sticks.
