Future value 1000 a year from now.  We are expected to pay about 6% less today to get the future value.
So the answer should be around $940, which makes an easy choice.

However, to make sure, we use the compound interest formula:
F=P(1+i)^n
where i=6%/12=0.005  [monthly interest]
n=1year * 12 months / year = 12 months

1000=P(1.005)^12
=>
P=1000/1.005^12=$941.91  is what needs to be deposited today.
