Answer:

B. $y= 5 - \frac{5}{7} x$

Step-by-step explanation:

okay, so you are trying to get y alone on one side. The first thing you want to do is try to get 7y alone on one side. You do that my subtracting 5x on both sides. You get 7y = 5x +35

Then you divide 7 on both sides and get y = -5/7x + 5

Andrews [41]

Answer:

$1619

Step-by-step explanation:

From the first statement, he sold 150 shares at $10.98 per trade, this means the total amount in which the sale cost is 10.98 × 150 =

$1647

Now we are told that the broker charged an amount of $28 per trade. Hence , the amount left after the broker had removed his charges is the total amount minus the broker fee.

That equals, 1647 - 28 which is $1619
