Ah hah ! NOW I see it. Thanks to BellBell for a good link.
My first impression is a dog bone standing up on one end.
You're talking about the area of the figure, so I'll think that over
before I look at the choices.
I see:
-- 2 semi-circles = 1 whole circle.
and
-- (1 rectangle) minus (a trapezoid).
Now I'll look through the choices.
A). No good. The trapezoid is cut OUT of the figure,
and shouldn't be added into it.
B). Oh ! Yes ! I didn't look at it that way at first, but
I can see how that works. 'B' is good.
C). and D). Yes. This was my description above.
So 'A' is the method that's wrong.

Answer:
D
Step-by-step explanation:
The blank should be the power of -4, so the statement is 1.7 x 10^-4 = 0.00017.
Steps:
1) 4,000 * .045 = 180
2) 180 * 6 = 1,080
3) 4,000 + 1,080 = 5,080
4)4,000 * .049 = 196
5) 196 * 6 = 1,176
6) 4,000 + 1,176 = 5,176
7) 5,176 - 5,080 = $96
Answer= $96
