At a graduation dinner, an equal number of guests were seated at each of 12 large tables, and 8 late-arriving guests were seated at a smaller table. There were 128 guests in all. If n represents the
number of people seated at each of the large tables, what equation could you use to find the value
of n?

OA. 12n - 8 = 128
OB. 12n + 8 = 128
OC. 8n + 12 = 128
OD. 8n - 12 = 128
