Question

A school ordered 3 large boxes of board markers. After giving 15 markers to each of 3 teachers, there were 90 markers left. The diagram represents the situation. How many markers were originally in each box?

Answer 1

Answer:

45

Step-by-step explanation:

Given

The school orders three boxes of markers

let the number of markers in each box be x

So total markers= 3x

School gives 15 markers to 3 teachers

So total markers given= 15×3=45

Markers left= 90

Total markers- markers given to teachers= markers left

So the equation will be

3x-45=90

3x=90+45

3x=135

x=135/3

x= 45

Ans) Markers originally in each box= x= 45

Hope this helps!!
