Answer:
Let a be no. of adults and b be no.
of children entered the small fair.
Total number of people enter the
fair: a + b = 2200
Total income: 4a + 1.5c = 5050
Solving the systems of equations, we have:
a = 2200 - c
4(2200 - c) + 1.5c = 5050
8800 - 4c + 1.5c = 5050
8800 - 2.5c = 5050
-2.5c = -3750
c = 1500
Then:
a = 2200 - 1500 = 700
