At the movie theatre, child admission is $5.10 and adult admission is $9.00 . On Wensday, twice as many adults tickets as child tickets were for a total of $831.60.

How many child tickets were sold that day?

36 child tickets were sold that day

Step-by-step explanation:

Hello,

let's say that x is the number of child tickets

then we have 2*x adults tickets and

5.10 * x + 9 * 2*x = 831.60

(5.10+18)*x = 831.60

x = 831.60 / 23.10 = 36

hope this helps
