Answer:
So adult tickets cost £17.00 and child tickets cost £9.00
Step-by-step explanation:
2a+3c=61
2a=61-3c
a=30.5-1.5c
...
3a+5c=96, using a found above we get:
3(30.5-1.5c)+5c=96
91.5-4.5c+5c=96
91.5+0.5c=96
0.5c=4.5
c=9, and since a=30.5-1.5c
a=17
So adult tickets cost £17.00 and child tickets cost £9.00
Answer:
The adult tickets cost £17.00 and child tickets cost £9.00
Step-by-step explanation:
2a + 3c = 61
2a = 61 - 3c
a = 30.5 - 1.5c
3(30.5 - 1.5c) + 5c = 96
91.5 - 4.5c + 5c = 96
91.5 + 0.5c = 96
0.5c = 4.5
c = 9
a = 30.5 - 1.5c
a = 17
The adult tickets cost £17.00 and child tickets cost £9.00
