Answer:
Adult ticket = $4,5
Student ticket = $3
.
Step-by-step 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
[tex]y = \frac{87}{29}[/tex]
[tex]y = 3[/tex]
.
Substitute the value of y to one of equations
[tex]10x + 9(3) = 72[/tex]
[tex]10x + 27 = 72[/tex]
[tex]10x = 72 - 27[/tex]
[tex]10x = 45[/tex]
[tex]x = \frac{45}{10}[/tex]
[tex]x = 4,5[/tex]
.
Happy to help :)
