Algebra.Com's Answer #670137 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! The general formula is A (at end)=d (deposit)(1+(r/n)^nt-1)/(r/n); where r is the rate, n the number of compoundings per year and nt is the total number of compoundings. \n" ); document.write( "A=d [{1+(.065)/12))^108-1)]/(.065/12) \n" ); document.write( "A=d[(1.792)-1]/(.065/12)=81,000, but don't round yet \n" ); document.write( "multiply through by (0.065/12) without rounding \n" ); document.write( "438.75=d(1.792-1); \n" ); document.write( "d=$553.87 \n" ); document.write( " |
