Answer:
24 g + 20 s = 520
3 possible ordered pairs are
(0 general, 26 student/senior)
(10 general, 14 student/senior)
(20 general, 2 student/senior)
Step-by-step explanation:
general admission = 24
student/senior = 20
24 g + 20 s = 520
let g = 0
20 s = 520
divide by 20
20s/20 = 520/20
s =26
if no general admission are sold 26 senior/student are sold (0,26)
(g=0,s=26)
let g=10
24*10 + 20s = 520
240 + 20s = 520
subtract 240 from each side
20s = 520-240
20 s = 280
divide by 20
s = 280/20
s=14
(10,14) (g=10,s=14)
let g=20
24*20 + 20s = 520
480 + 20s = 520
subtract 480 from each side
20s = 520-480
20 s = 40
divide by 20
s = 40/20
s=2
(20,2) (g=20,s=2)
