· The amount of commission Joe paid his broker when he bought the stock. (Amount he paid for stocks* commission in percent)

·The amount that Jim sold the stock for. (number of shares * selling price)

·The amount of commission Joe paid his broker when he sold the

stock. (Amount he sold shares * commission in percent)

· Calculate the amount of money Joe had left when he sold the stock and paid his broker (both times). If this amount is positive, then Joe made a profit. If the amount is negative, then Jim lost money.

· Profit/loss =(amount paid to buy stocks + commission) – (amount for sold stocks– commission)

·The amount of commission Joe paid his broker when he sold the stock. (Amount he sold shares * commission in percent)

· Display the amount of money Joe had left when he sold the stock and paid his broker (both times). If this amount is positive, then Joe made a profit. If the amount is negative, then Jim lost money.

Profit/loss =(amount paid to buy stocks + commission) – (amount for sold stocks– commission)
