Let cost of adult ticket = x 

And cost of student ticket= y 

Jacob's purchase, 

4x + 2y = 64 ....(1)

Tatianna's purchase, 

3x+3y = 60 ......(2) 

Multiplying equation 1 from 3 and equation 2 from 4 and subtracting them, 

12x+6y - 12x - 12y= 192 - 240 

-6y = -48

y = $8 

Putting the value of y in equation 1,

4x + 2×8 = 64 

4x = 64-16 

4x = 48

x = 48/4 

x = $12
