The present worth of a cash flow of $$1,000$ that occurs every $10$ years forever, with the first one

occurring now with $i\%$ per year is:

a$.$ $$1,000+\{$$$1,000\frac{\frac{A}{F},i\%,10}{i}\%\}$

b$.$ $$1,000+\{($$$1,\frac{000}{i}\%)10\}$

c$.$ $$1,000\frac{\frac{A}{F},i\%,10}{i}\%$

d$.$ $$1,000+\{$$$1,000\frac{\frac{A}{P},i\%,10}{i}\%\}$
