Erin wants to train 32 hours during his first conditioning month. He trained 9 hours in the gym during first week and 11 hours during second week. Which equation represents the number of hours Erin still has to train to reach his goal?

Given data:
The number of hours Erin trains in the first week is a=9 h.
The number of hours Erin trains in the second week is b=11 h.
The total hours in the training are n=32.
The given expression can be written as,
9+11+h=32.
Thus, option C) is correct.
