Answer:
x = 144 children
y = 160 adults
Explanation:
We have parameters already defined. Number of children that entered is x while number of admitted adults is y.
Since the total number of people admitted was 304, this means:
x + y = 304
Total fees for that day was 856
Mathematically:
1.5x + 4y = 856
From the first equation, we can say y = 304 - x
We then substitute this into the second equation:
1.5x + 4(304 - x) = 856
1.5x + 1216 - 4x = 856
1216-856 = 4x-1.5x
2.5x = 360
x = 360/2.5 = 144
Since y = 304 - 144
y = 160
The number of children admitted was 144 and the number of adult is 160
