child admission is $5.60 and adult admission is $8.90. 124 tickets were sold for a total sales of $859.40. How many child tickets were sold that day?

Answer 1

x= child tickets sold

y= adult tickets sold

x+y = 124

y= 124-x

5.6x + 8.90y = $859.40

5.6x + 8.9(124-x) = $859.40

5.6x +1103.6 -8.90X = $859.40

$244.2 = 3.3x

x = 74
