Tickets to a local performance sold for $3.00 for adults and $1.50 for children. If 170 tickets were sold for a total of $480 dollars, how many adult and children tickets were sold?

a + c = 170
3 a + 1.5 c = 480
a = 170  c
3 (170  c) + 1.5 c = 480
510  3 c + 1.5 c = 480
30 = 1.5 c
c = 20
then a = 150
