Apologies for the mistake in my previous response. Upon reviewing the inequality again, the correct answer is that there is no letter coefficient in the inequality "Ba + 72 < 12". The "Ba" term is a combination of the letters "B" and "a" but does not have a coefficient (a number multiplying the term) attached to it.
Well you are wrong
I apologize for the incorrect response. In the inequality "Ba + 72 < 12", the term "Ba" does indeed have a letter coefficient. The coefficient is 1, as there is an implicit 1 multiplying the letter term "Ba".
In the inequality "Ba + 72 < 12", the term "Ba" is a letter coefficient.
