The correct answer is $216 because when 7 tickets cost $126 each ticket was $18. I know this because 126/7 is 18. Now to find out how much 12 tickets cost you multiply 18x12 to get 216.
Biconditionals are statements that work both ways.
Some examples:
If it rains, I go out, and if I go out, it must be raining.
This can be stated concisely in mathematical terms as
I go out IF AND ONLY IF it rains.
So looking at the given statements, only the last two work both ways, namely:
If the sun rises in the east, then it is morning, and if it is morning, the sun rises in the east.
Victoria will play outside if and only if the weather is nice.
