Answer:

80 tickets

Step-by-step explanation:

Adult tickets = A (cost $8)

student tickets = S (cost $4)

A = S + 20 (20 more adult tickets than student tickets)

Total amount = $880  

$8A + $4S = 880

New equation:  

$8(S+20) + $4S = 880  

$8S + 160 + $4S = 880

$12S = 720

S = 60

Next we find the adult tickets by substituting back:

A = S + 20

A = 60 + 20

A = 80
