Jose mendez bought 200 shares of stock at a quotation of 24.5. the brokerage fee was $139. what was the total cost?

For this case we have that the total cost is:
 C = (shares) * (quotation) + (brokerage fee)
 Substitute the values we have:
 C = (200) * (24.5) + (139)
 C = 4900 + 139
 C = 5039 $
 
 the total cost was:
 C = 5039 $

Ibelieve the total for the tip could be $21.90
