    Answer: 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:

    662.5=85x+65y                …..(1)

    x=2.5y                                ……(2)

    Putting value of ‘y’ from equation 2 to equation 1:

    662.5=85(2.5x)+65y\\\\662.5=271.5y\\\\y=\frac{662.5}{271.5}=\$ 2.44

    Now, solving for ‘x’, we get:

    x=2.5(2.44)=\$ 6.1

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