The money altogether is 8.00$
Y=3x-9
0=3x-9
-3x=-9
x=3
X-int = 3
3 - 15 = -12
so that is your answer
It is 6,5. So uh how’s your day lol. Sorry I have to type more to answer your question but the answer is 6,5
The answer is $3990 heres why
First you need to find out what is the total you paied for the shares
$18.12x200= $3624
Then you need to add the flat fee to the spending chost
$3624+$30= $3654
Now you re-mulitply the chost per stock to the tootle #'s of stock you sold
$21x200= $4200
Then you need to find out what how much you need to pay the stock broker
$4200x.05= $210
Then once you find out how much you need to pay him subtract that amount to the total money earned from selling your stocks
$4200-$210= $3990
Then if you want to also find out your profit just subtract the total amount you payed for the stock and subtract it from the total amount you gained from the stock.
$3990- $3654= $336 Profit
