At the movie theatre, child admission is $5.20 and adult admission is $8.60 . on thursday, twice as many adult tickets as child tickets were sold, for a total sales of $868.00 . how many child tickets were sold that day?

The number of child tickets = 39

Step-by-step explanation:

It is given that,child admission is $5.20 and adult admission is $8.60

Total sales = $868.00

To find the number of child tickets

Le 'x' be the number of children then number of adults = 2x

(x * 5.20) + (2x * 8.60) = 868

5.2x + 17.2x = 868

22.4x = 868

x = 868/22.4

 = 38.75 ≈ 39

Therefore the number of child tickets = 39
