Question

Set up and solve the system of equations using

Answer 1

54 tickets on parents

Answer 2

I dont know about everyone but I solved and got 90.
Remember each ticket costs 2.50, then the school used $225. So what I did is I divide 225 to 2.50 which gets 90 and that’s how many tickets were sold to parents. How I checked my answer, I times $2.50 for 90 tickets, which still equals to $225 so yeah that’s it...
