Question

At the movie theatre, child admission is $5.20 and adult admission is $9.00. On Friday, twice as many adult tickets as child tickets were sold, for a total sales of $696.00. How many child tickets were sold that day?

Answer 1

Answer:

30

Step-by-step explanation:

Let the number of child tickets sold be $x$, then the number of adult tickets sold will be $2x$.

Then the amount made from child tickets will be $5.2x$, and $(9*2x)=18x$ for adults.

So we have

$5.2x+18x=696\\23.2x=696\\x=30$

So 30 child tickets were sold that day.
