Answer: 5,600
Explanation: By multiplying 0.10 (4,000) to find the interest for one year, you get 400. Because she is using this loan for 4 years you multiply that one year interest by 4. 400 times 4 is 1600. Then, you add that 1600 (which is the total interest for 4 years) to the loan, to get an answer of 5,600.

Answer: correct choice is D.
The second quadrant is the quadrant in the top left when looking at a graph. If the figure were to be reflected across the y-axis (the vertical axis), then that figure would end up in the top right quadrant, which is the first quadrant. :)
