Eric and Mark went to a ball game and visited the concession stand. They each got a hot dog, and mark got a large soda and a bag of peanuts. Eric had a coupon for 3$ off the cost. Mark Paid for the rest, which came to 11.50. Peanuts cost 4$, and a hotdog costs 3.50. What is the cost for a large soda?
