Eric and mark were at a ball game and visited the concession stand. they each got a hamburger, and mark got lemonade and some cotton candy. eric had a coupon for $2 off the cost. mark paid the rest, which came to $14.50. cotton candy costs $5, and a hamburger costs $4. how much is lemonade? (1 point)
7.5 1.5 4 $3.50***

So here is the answer. Given that both Eric and Mark got a hamburger which is $4 each. Mark got a lemonade and some cotton candy which costs $5. 
So this gives them a total of $4, $4, $5, $?(lemonade). Partial sum is $13 without the lemonade. Since Eric got a $2, the total bill was deducted with $2 and the rest of the amount is $14.50. Therefore, the total bill would have been $16.50. So $16.50 minus $13 (partial sum) is $3.50. So the lemonade costs $3.50. Hope this helps.
