Child tickets are $6.30, adult tickets are $9.80. 172 tickets were sold for a total of $1,346.10. How many adult tickets were sold?

Answer 1

x is the child tix

y is the adult tix

X+Y = 172 --> Y = 172 - x

6.3X + 9.8Y = 1346.19

6.3X + 9.8 ( 172 - x) = 1346.10

6.3x + 1685.6 - 9.8x = 1346.10

-3.5x = -339.50

x = 97

y = 75

yes it checks
