Question

a total of 528 tickets were sold for the school play. they were either adult tickets or student tickets. the number of student tickets sold was three times the number of adult tickets sold. how many adult tickets were sold?

Explanation:

Step1: Let adult tickets be $x$.

Let the number of adult tickets be $x$. Since the number of student tickets sold was three times the number of adult tickets sold, the number of student tickets is $3x$.

Step2: Set up equation.

The total number of tickets sold is 528, so $x + 3x=528$.

Step3: Simplify the left - hand side.

Combining like terms, we get $4x = 528$.

Step4: Solve for $x$.

Dividing both sides of the equation by 4, $x=\frac{528}{4}=132$.

Answer:

132
