Answer:
c = 202 children use the pool, and 284 - 202, or 82 adults.
Explanation:
Represent the number of children by c and the number of adults by a.
There are a total of 284 people using the pool, so c + a = 284.
Admission fees are $1.50/child and $2.00/adult. $1.50c is the amount taken in through ticket sales for c children; $2.00a for adults.
Then total ticket sales are ($1.50/child)c + ($2.00/adult)a = $467.
Going back to c + a = 284, a = 284 - c, and so the above equation becomes
($1.50/child)c + ($2.00/adult)(284 - c) = $467
After simplifying this equation in c, we get:
1.50c + 568 - 2c = 467, or
101 = 0.5c. Thus, c = 202 children use the pool, and 284 - 202, or 82 adults.
