Question 1161437
.
<pre>

Let's find the number of adults, x, first.


If the number of adults is x, then the number of children is (116-x).


Then your equation is for the total money

    3x + 2.75*(116-x) = 335.25.


From this equation

    x = {{{(335.25-2.75*116)/(3-2.75)}}} = 65 adults.


Then the number of children is 112-65 = 47.
