The number of child ticket sold on that day is 69.
How to find the number of ticket sold using variables?
At the movie theatre, child admission is $5.80 and adult admission is $9.30 . On Wednesday, 122 tickets were sold for a total sales of $893.10 .
Therefore,
let use variables to represents the number of child and adult tickets sold.
let
variable x = number of child ticket sold
variable y = number of adult tickets sold
Therefore,
5.80x + 9.30y = 893.10
x + y = 122
multiply equation(ii) by 5.80
5.80x + 9.30y = 893.10
5.80x + 5.80y = 707.6
3.5y = 185.5
y = 185.5 / 3.5
y = 53
Therefore,
x = 122 - 53
x = 69
Hence, the number of child ticket sold on that day is 69.
