Answer:
188 children and 145 adults were admitted in the park.
Step-by-step explanation:
Given:
The admission fee at an amusement park is $1.50 for children and $4 for adults.
Total $862 collected on a certain day when 333 people enter the park.
Now, to find the children and adults admitted in the park.
Let the number of children admitted be [tex]x.[/tex]
And the the number of adults admitted be [tex]y.[/tex]
So, the total people enter the park:
[tex]x+y=333\\\\x=333-y\ \ \ ...(1)[/tex]
Thus, the total amount collected of the admission fee:
[tex]1.50(x)+4(y)=862\\\\[/tex]
Substituting the value of [tex]x[/tex] from equation (1):
[tex]1.50(333-y)+4(y)=862\\\\499.50-1.50y+4y=862\\\\499.50+2.50y=862\\\\Subtracting\ both\ sides\ by\ 499.50\ we\ get:\\\\2.50y=362.50\\\\Dividing\ both\ sides\ by\ 2.50\ we\ get:\\\\y=145.[/tex]
Thus, the number of adults = 145.
Now, to get the number of children by substituting the value of [tex]y[/tex] in equation (1) we get:
[tex]x=333-y\\\\x=333-145\\\\x=188.[/tex]
Hence, the number of children = 188.
Therefore, 188 children and 145 adults were admitted in the park.
