child admission is $5.90 and adult admission is $9.10. 175 tickets were sold for a total sales of $1282.10. How many child tickets were sold that day?

Child tickets are 97

Step-by-step explanation:

x + y = 175 ... (1)

x = 175 - y

5.90x + 9.10y = 1282.10 ... (2)

5.90 (175 - y) + 9.10y = 1282.10

1032.50 - 5.9y + 9.10y = 1282.10

3.2y = 249.60

y = 249.6. / 3.2

y = 78

From equation 1

x + y = 175

x + 78 = 175

x = 175 - 78

x = 97
