Question

You are buying markers for the students in first grade. Each student will get 5 markers. There are 16 students in one class and 19 students in the other class. How many markers do you need to buy?

Answer 1

52 markers that you will need to buy.

Answer 2

You would need to buy 175 markers

5 markers (each student gets 5) times 16 (cause there's 16 students in class)=80 markers needed for the first class

5 markers (each student gets 5) times 19 (cause there's 19 students in the class)=95 markers needed for the second class
 
Add both together 80+95 and u get ur answer which is 175 markers 

Hope this helps! :)
