The mean is 80
Answer:
There are 18 seniors and 25 juniors.
Step-by-step explanation:
- Find your equation. For this equation, it comes out to be:
x + x + 7= 43 or 2x+7=43
X represents the amount of seniors.
The amount of juniors can be represented as x+7
- Solve the equation. It comes out to be:
1st - Transfer the 7 to the other side to get the x by itself
2x=36
2nd - Divide 36 by 2 to leave x by itself
x=18
- Answer the question. Because you didn't specify what your were asking for, I imagine it's the number of player from each class.
Because x represents the seniors, there are 18 seniors.
There are 7 more juniors, add 7 to 18, so there's 25.

You need to subtract 25 by 18
