The total number of labels collected by the students in the third month is equal to 525 by the equation 3 x + x = 2100.
Let the number of labels collected in the first two months be 3 x.
We are given that the number of labels collected in the first two months was three times the number of labels collected in the third month.
So, the number of labels collected in the third month = 3 x / 3 = x
Now, we are also given that:
The total number of labels collected by the students at the school = 2100.
So, we get the equation as:
3 x + x = 2100
4 x = 2100
x = 2100 / 4
x = 525 labels.
Therefore, we get that, the total number of labels collected by the students in the third month is equal to 525 by the equation 3 x + x = 2100.
