Okay, let's break this down step-by-step:
Sophia has a debt of 54.98
Lilly has a positive balance of 39.56
Norman owes 32.00 to the bank
Christopher has a positive balance of 116
So:
Sophia's balance: -54.98
Lilly's balance: 39.56
Norman's balance: -32
Christopher's balance: 116
To get the total balance of the 4 friends:
-54.98 + 39.56 - 32 + 116 = 79.58
So the total balance of the 4 friends is 79.58
