student ticket?

The cost of adult ticket is $6.1 and that of student ticket is $2.44

Step-by-step explanation:

Let the cost of adult ticket be 'x' and cost of student ticket be 'y'

From the question, the equations formed are:

               .....(1)

                               ......(2)

Putting value of 'y' from equation 2 to equation 1:

Now, solving for 'x', we get:

Hence, the cost of adult ticket is $6.1 and that of student ticket is $2.44
