<h2>
The correct option is : B) y = 200 + 4 c - 6 b</h2>
Step-by-step explanation:
Here, the given question is <u>incomplete</u>.
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
