At the movie theatre, child admission is

$5.70

and adult admission is

$9.80

. On Thursday, twice as many adult tickets as child tickets were sold, for a total sales of

$556.60

. How many child tickets were sold that day?

Child = $5.70

Adult = $9.80

- We can conclude that the amount of adult is double the amount of child tickets bought. (total of $556.60)

For this, you will need to divide the total amount by two and draw a tree chart with each of the numbers to get the seperation of the two. I would find out how many 9.80s or 5.70s go into $56.60 so you'll just have $500
