At a wedding reception, an equal number of guests were seated at 12 round tables. The 13 people in the wedding party were seated at a rectangular table. There were 121 people at the reception altogether. Which equation could you use to find the number of guests, n, seated at each round table?

Respuesta :

It is 9
My explaination-
121-13 due to the ones already seated is 108, 108/12=9
12n + 13 = 121
-13 from both sides

12n = 108
÷12 from both sides

n=9
