Answer: a. $1,504.17
Step-by-step explanation:
Cost of Acquiring Shares at $30.60 per share.
=$30.60*621
= $19,002.60
Gain from Selling shares at $36.23 per share.
= $36.23*621
= $22,498.83
Brokerage fee at $48 per $1000 of stock bought or sold.
Here we can calculate both figures together being Melanie's cost of buying and selling.
= (19,002.60/1000 + 22,498.83/1000) * 48
= (19.00260 + 22.49883) * 48
= $1992.07
Net Profit from sale of shares.
= 22,498.83 - 19,002.60 - 1992.07
= $1,504.17.
$1,504.17 was Melanie's Profit
