Matt has 8 baseball cards worth $6 each. If he trades two of them to Jane in exchange for 3 $2 cards and 1 $9 card, how much profit does he make? Let's answer step by step:
First find the value of the 2 cards Matt trades: $6 / card * 2 cards = $12. Then find the total value of the 3 $2 cards: 3 cards * $2 / card = $6. Then subtract the value of the cards Marcus gave up from the value of the cards he gained to find his profit: $9 + $6 - $12 = $3. The answer: 3.
