Answer:
student tickets cost $4.50
adult tickets cost $7.00
Explanation:
a = cost of an adult ticket
s = cost of a student ticket
(1) 68a + 136s = 1088
(2) 79a + 140s = 1183
solve (1) for a:
68a = 1088 - 136s
a = 16 - 2s substitute this into (2):
79(16-2s) + 140s = 1183
1264 - 158s + 140s = 1183 solve for s:
-18s = -81
s = -81/-18 = 4.50 plug this into either equation 1 or 2 to solve for a:
68a + 136(4.50) = 1088
68a = 1088 - 612 = 476
a = 476/68 = 7.00
