A total of 190 people attended the opening night of a schoolmusical. Student tickets cost $\$4.50$ each while general admission tickets cost $\$6$ each. If total sales were $\$996$, how many general admission tickets were sold?
Let the nuber of student tickets = 190 - x
Let the number of general admission tickets = x
So
6x + 4.50 (190 -x) = 996 simplify
6x + 855 - 4.50x = 996
6x -4.50x = 996 - 855
1.50 x = 141
x = 141 / 1.50 = 94 = general adm tickets sold
