Question

I need help solving a math problem.A total of 516 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold were three times the number of adult tickets sold. How many adult tickets were sold?

Answer 1

The total number of tickets sold = 516.

Let the number of student tickets sold be S.

Let the number of adult tickets sold be A.

According to the given condition,

$S\text{ = 3A \_\_\_\_\_\_\_\lparen1\rparen}$

Also,

$\begin{gathered} A+\text{ S = 516} \\ A+\text{ 3A = 516} \\ 4A\text{ = 516} \\ A\text{ = 129} \end{gathered}$

Thus 129 adult tickets were sold.
