Question $2$

Darwin is a young entrepreneur trying to keep his business afloat. He has missed two payments to a creditor. The first was for $$3,485$ seven months ago, and the second was for $$5,320$ last month.

Darwin has had discussions with his creditor, who is willing to accept $$4,000$ one month from now and a second payment in full six months from now.

If the agreed upon interest rate is $7\mathrm{.}35\%$ compounded monthly, what is the amount of the second payment?
