Answer:

Adult ticket = $4,5

Student ticket = $3

.

Explanation:

Let say adult ticket is x and student ticket is y. so we get:

→ 8x + 13y = 75 (×5) 40x + 65y = 375

→ 10x + 9y = 72 (×4) 40x + 36y = 288

.

Eliminate both equations

40x + 65y = 375

40x + 36y = 288

29y = 87


y = (87)/(29)


y = 3

.

Substitute the value of y to one of equations


10x + 9(3) = 72


10x + 27 = 72


10x = 72 - 27


10x = 45


x = (45)/(10)


x = 4,5

.

Happy to help :)
