A consultant charges $30 for each hour she works on a consultation, plus a flat $45 consulting fee. Which equation could be used to find how many hours of work are included in a $210 bill for a consultation?

Let's say the number of hours worked is represented by h. The equation that could be used to find the number of hours of work included in a $210 bill for a consultation would be:

30h + 45 = 210
