Question

A total of 304 tickets were sold for the school play. They were either adult or student tickets. The number of student tickets were sold was three times the number of the adult tickets sold. How many adult tickets were sold?

Answer 1

A means #of adult tickets
S means # of student tickets

304=a+S
S=3•a
Plug the second equation into the first
304=a+3•a
301=2a
150.5=a

Plug a into one of the equations to find the students
304=150.5+S
153.5=S

Hope it helps ❤️
