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) e)

B) 200 + 4c - 6b

Step-by-step explanation:

Be,

c = number of cards sold at $4

b = number of cards purchased at $6

x = money at the beginning of the day = $200

y = money at the end of the day

The variables x and c owe positive values because they represent possession or income of money, while b must be negative because purchases are expenses.

Then, the following equation is formed:

y = x + 4c - 6b

Substituting x for its value, you get

y = 200 + 4c - 6b

Hope this helps!
