Sally and Anne both needed a ticket, so each paid $9 for the ticket.
Then they each bought a drink costing $1.35.
But they shared popcorn and a veggie cup costing $3.50+$1.74, so the cost to each woman was ½(3.50+1.74).
We're looking for 9+1.35+½(3.50+1.74) in the answer. So answer 2 must be the right answer!
