Answer :
The price of one senior citizen ticket is $7 and the price of one child ticket is $8.
What are the linear equations that represent this question?
s + 13c = 111 equation 1
12s + 9c = 156 equation 2
Where:
- c = price of one child ticket
- s = price of one senior citizen ticket
What is the price of one children's ticket?
Multiply equation 1 by 12
12s + 156c = 1332 equation 3
Subtract equation 2 from equation 3
1176 = 157c
c = $8
What is the price of one senior citizen's ticket?
Substitute for c in equation 1:
s + 13(8) = 111
s = 111 - 104
s = $7
