110 students

Step-by-step explanation:

Let the total money raised = R ($)

Let the number of student = x

Proposed ticket cost to activity night = $5

(a) R = 5x

     x = R/5 (1)

(b)  Total money to be raised to pay for rent  of $200 and have a left over of  $ 350 is = $(200 + 350)

            R    = $ 550

Substituting the value of R in equation (1), the number of student (x) can be found:

x = R/5

  = 550/5

 = 110 students

The student council must sell 110 tickets to students in order to achieve their goal.
