Answer:

83.56/p

Step-by-step explanation:

Let the weight of the players = p

Let the weight of the reserve players = r

Since there 9 players, there weight = 9p

And since there 3 reserve players, there weight = 3r

(9p + 3r) / 12 = 188

9p + 3r = 12 * 188

9p + 3r = 2256

Solve for r

r = 2256 / 27p

r = 83.56/p
