Answer:
"A - $32.50"
Step-by-step explanation:
So, 0.40 per share for 100 shares is:
Decrease of 0.40 * 100 = $40
Also, 0.25 per share for 30 shares is:
Increase of 0.25 * 30 = $7.5
So, decreased by 40 and increased by 7.5 means Total Decrease of 40 - 7.5 = $32.5
Answer choice A is right.
9 equals 90,000 its in the ten thousands place
Let the length = x
2 lengths are 2x.
Then you have 400 - 2x for both widths, so the width is 200 - x.
The are if the rectangle is
y = x(200 - x)
y = 200x - x^2
y = -x^2 + 200x
Take the first derivative ans set equal to zero to find a maximum value.
y' = -2x + 200
-2x + 200 = 0
-2x = -200
x = 100
Since the side of the rectangle is 100, all sides measure 100 ft, and you have a square.
The maximum area is 100 ft * 100 ft = 10,000 ft.
5 x 3 = 15
30 x 3 = 90
15+90=105
so that person paid $105 for that day
