You owed $$925\mathrm{.}00$ six months ago, $$2000\mathrm{.}00$ in five months, and $$1000\mathrm{.}00$ in seven months. If you made a single payment today to pay off the $$925$ you owed four months ago $($and left the rest$),$ how much is the single payment if money is worth $7\mathrm{.}5\%$ p$.$a$.$ and the agreed focal date is today?
