Answer :
The number of children that were admitted = 196
The number of adults that were admitted = 160
Given that,
The admission fee at an amusement park for children = $1.25
The admission fee at an amusement park for adults = $6.80
On a certain day, people entered the park = 356
The admission fees collected totaled = $1333
Let us assume,
The number of children that were admitted represented as = x
The number of adults that were admitted represented as = y
On a certain day, 356 people entered the park.
So,
We can write,
x + y = 356
x = 356 - y (Equation-1)
The admission fee at the amusement park is $1.25 for children and $6.80 for adults.
The admission fees collected on that day totaled $1333.
Then the,
1.25x + 6.8y = 1333 (Equation-2)
Substituting x = 356 - y into equation 2, it becomes
1.25x + 6.8y = 1333
1.25(356 - y) + 6.8y = 1333
445 - 1.25y + 6.8y = 1333
-1.25y + 6.8y = 1333 - 445
5.55y = 888
y = 888 / 5.55
y = 160
Then we can substitute y value in equation - 1,
x = 356 - y
x = 356 - 160
x = 196
Therefore,
The number of children that were admitted = 196
The number of adults that were admitted = 160
