Question 985266


Let &nbsp;<B>x</B>&nbsp; be the number of children attended. &nbsp;Then the number of adult attended is &nbsp;3<B>x</B>, &nbsp;according to the condition.


Then you have an equation 


x + 3x = 300.


Solve it:


4x = 300,


x = {{{300/4}}} = 75. 


Thus &nbsp;75&nbsp; children were in attendance and &nbsp;3*75 = 225 adults.
