1. 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

There was 45 markers originally in each box.
How do we know?
Well, 3*x = 15*3 + 90 = 45 + 90 = 135
Divide both of the sides by 3
X = 135/3 = 45
Therefore, that’s how we know that there was 45 markers originally.
