Answer 8

You start with 2 cents, and will end at 2*365 cents.

So you have \(2+4+6+\cdots+730\)

You can factor 2 out and you will have \(2(1+2+3+\cdots+365)\).

You can use formula \(1+2+3+\cdots+n=\dfrac{n(n+1)}{2}\)

Answer 9

So it all went down to \(365\times366\)

Answer 10

then divide it by 100 to change unit from cents to dollars.
