Answer:
30 adult tickets and 24 kid tickets
Step-by-step explanation:
set up equations
x=adult tickets
y=kid tickets
x(adult tickets)+y(kid tickets)=54(people in total)
x+y=54
$8x+$5y=$360
$8 per ticket for adults
$5 per ticket for kids
total of $360 earned
8x+5y=360
↓
x+y=54
8x+5y=360
solve by elimination or substitution or even graph to get
(x,y)=(30,24)
x=30
y=24
