Answer:
93 child tickets
Step-by-step explanation:
Create a system of equations where c is the number of child tickets sold and a is the number of adult tickets sold:
c + a = 171
5.80c + 9.70a = 1296.00
Solve by elimination by multiplying the top equation by -9.7:
-9.7c - 9.7a = -1658.7
5.8c + 9.7a = 1296
Add these together and solve for c:
-3.9c = -362.7
c = 93
So, 93 child tickets were sold.
