X= number of student tickets

Y= number of on student tickets

x+y=311

0.50x + 1.50y = 385.50

Solve x in 1st equation

X+y=311

X= -y + 311

Now substitute x into second equation to solve for y

0.50(-y+311)+ 1.50y = 385.50

-0.50y+311.50+1.50y=385.50

Y+311.50=385.50

Y= 385.50-311.50

Y= 74

Now substitute y answer to first equation to find x

X+y=311

X+ 74=311

X= 311-74

X= 237

So 237 students tickets and 74 non students tickets
