Question

The chess club members bought 6 tickets to a tournament for $15. How much would they have paid if all 9 members wanted to go?

Answer 1

For nine members, it would cost `22.50`

Explanation:

So we would set it up as a proportion to solve for x like this:

`"6 tickets"/"$15"` = `"9 tickets"/x`

So "tickets" refer to people. So since they brought 6 tickets for 6 people for 15 dollars, we need to cross multiply to see what we would get for `x`.

`15*9=135` then `135/6=22.25`

So for 9 members (or tickets), it would cost 22.50
