Answer:
There are both on the same side of the image "O and P"
If this dose not help please tell me!
I'd say neither because 5.82-4.21 equals to 1.61, and it does not go above 2 as an overestimate. In addition, it's not an underestimate because 1.61 rounds up to 2. If you can't put that as an answer, you can say its an underestimate because it does not meet the real standards of being 2.
Let's calculate how much do you spent paying monthly $165:
24*165=3960 ($)
If you pay cash you will spent $3438
The difference between those two is how much you save paying cash:
3960 - 3438 = 522 ($)
The answer is C.
