Ron sold #9# students tickets

Let #x# be the number of student tickets Ron sold then

#16-x# will be the number of adult tickets sold by Kathy

Now, the total income of both Ron & Kathy

#1\cdot x+5.5(16-x)=47.5#

#x+88-5.5x=47.5#

#4.5x=88-47.5#

#x=40.5/4.5#

#x=9#

Thus, Ron sold #9# students tickets
