suppose you owe someone two sums up of money: $1000, due in two years, and $600, due in six years. if you wish to pay off the total debt now by a single payment, how much should you pay, assuming an interest rate of 8% compounded annually?​

You are given the following information about aggregate demand at the existing price level for an economy: (1) consumption = $400 billion, (2) investment = $40 billion, (3) government purchases = $90 billion, and (4) net export = $25 billion. if the full-employment level of gdp for this economy is $600 billion, then what combination of actions would be most consistent with closing the gdp gap here?
