Question 1132345
.
<pre>
If x is the number of the student tickets, then the number of the adult tickets is 3x.


The "revenue" equation is


3*x + 4*(3x) = 300


3x + 12x = 300


15x = 300  ====>  x = {{{300/15}}} = 20   student tickets.           <U>ANSWER</U>


Then the number of adult tickets is 3*20 = 60.              <U>ANSWER</U>

Solved.
