A community theater group put on a play last month. Twenty more adults attended than children. Adult tickets cost $8 each and children's tickets cost $3 each. The theater group collected $1,260. How many adults tickets were sold?

Respuesta :

x = number of children

8(x+20) + 3x = 1260
8x + 160 + 3x = 1260
11x = 1100
x = 100
x + 20 = 120 adult tickets
