Answer:
A: [2(200-x)]/3 B: 31.33333...
Step-by-step explanation:
A: Algebraic expression:
Let's say average = x
So the expression is [2(200-x)]/3
You have to take average away from 200, which is 200-x, you have to multiply that whole expression by 2, and then divide everything by 3.
B: Plug in 153 for x:
2(200-153)/3 and then just solve algebraically
=2(47)/3
=94/3
=31.33333...
