If you want to have $860 in 22 months, how much money must you put in a savings account today? Assume that the savings account pays 7% annually and it is compounded monthly (round to the nearest $1 and enter it like this $518)

I'm so close to answering this one I think. . . .? but I keep coming up with a PV that is greater than my FV which obviously doesn't make sense.
