Ответ:
The answer to your question is 175 adults and 148 children
Step-by-step explanation:
Data
Cost for children = $4.00
Cost for adults = $5.60
Total number of people = 323
Total fees = $1572
children = c
adults = a
Process
1.- write equations to solve this problem
c + a = 323 Equation l
4c + 5.6a = 1572 Equation ll
2.- Solve by elimination
Multiply equation l by -4
-4c - 4a = -1292
4c + 5.6a = 1572
0 1.6a = 280
a = 280/1.6
a = 175
-Find c
c + 175 = 323
c = 323 - 175
c = 148
3.- Conclusion
There were 175 adults and 148 children
