You are at a trade show where you are selling baseball cards for $4 a card and buying baseball cards for $6 a card. If you started the day with $200, how much money do you have at the end of the day if you sold c baseball cards and bought b baseball cards? A) 4c - 6b B) 200 + 4c - 6b C) 200 - 4c + 6b D) 200 - 2(c + b)

Here, the total number of cards sold = c

The cost of each card sold = $4

the total number of cards purchased = b

The cost of each card purchased = $6

The amount of money initially had = $200 = K

Let us assume the amount left at the end = y

So, the amount left :

= Total Money - ( Money spent on buying b cards ) + (money earned from selling c cards

The total amount earned after selling c cards at $4 each = 4 c

The total amount spent on buying b cards at $6 each = 6 b

So, the total money (y) left :

$200 + (4 c) - (6 b)

or, y = 200 + 4 c - 6 b

Hence, the correct option is : B) y = 200 + 4 c - 6 b
