    Answer:

    • 347 kids
    • 144 adults

    Step-by-step explanation:

    Let x represent the number of adults using the pool. Then 491 -x is the number of kids using the pool, and the total revenue is …

      2.25x +1.25(491 -x) = 757.75

      x +613.75 = 757.75 . . . . . . . . . eliminate parentheses, collect terms

      x = 144 . . . . . . . . . . . . . . . . . . . . subtract 613.75; number of adults

      491-x = 347 . . . . . number of kids

    347 kids and 144 adults used the pool.
