Now
if one is added i.e.

Now let us assume the other polynomial be x
So,


There are 8000 millimeters because 1 liter is also 1000 millimeters
We have the following table:
Round Number of Strokes Above or Below 72
1 -5
2 +6
3 -2
4 -4
5 +5
So, the expression that represents the total number of strokes is:
72 + (Number of strokes Above or below 72)
Therefore, for every round we get:
Round Number of Strokes Above or Below 72 Total number of strokes
1 -5 72 - 5 = 67
2 +6 72 + 6 = 78
3 -2 72 - 2 = 70
4 -4 72 - 4 = 68
5 +5 72 + 5 = 77
The total number of strokes is:
67 + 78 + 70 + 68 + 77 = 360
Additionally, the average is the total number of strokes divided by the number of rounds, so it is equal to:

Answer: Total: 360 Strokes
Average: 72 Strokes
There are 39 boys.
First you divide 4 into 52 because there are 3 boys for 4 girls.
Then you take the quotient, 13, and multiply by 3.
