Algebra.Com's Answer #692780 by jorel1380(3719)![]() ![]() You can put this solution on YOUR website! To answer this question, we use the formula P=payout[(1+r)^n -1]/r(1+r)^n, where P is the principal, r is the periodic interest rate, and n is the total number of periods. So, for this example, we have: \n" ); document.write( "P=2200[(1+.06/4)^16 -1]/.06/4*(1+.06/4)^16 \n" ); document.write( "P=591.76820483920722046352555284907 \n" ); document.write( "P=$31088.7808997 as the amount needed to fund the annuity properly. ☺☺☺☺ \n" ); document.write( " |
