Comment and Answer
This is a very well laid out proof. It would good for you to see how carefully this this proof has been set up.
Step Three says
DE = DF ÷ 2
The problem is that at least 2 of the choices will work. I think the best reason is that it is the definition of bisect. The previous statement says in language what statement three says in algebraic notation. So statement 2 is the given statement. Statement 3 tells us that DE is 1/2 DF because it is bisected.

Answer:
18,000 at 2%
22,000 at 3%
Step-by-step explanation:
x: the amount in account paying 2% interest
y: the amount in stock paying 3% interest
x + y = 40,000
2%. x + 3%. y = 1020
⇒ x = 18,000
y = 22,000
