Algebra.Com's Answer #763502 by greenestamps(13206) You can put this solution on YOUR website! \n" ); document.write( "Here is an alternative method for solving \"mixture\" problems like this that will get you to the answer much faster, and with far less effort, than the traditional algebraic method shown by the other tutor. \n" ); document.write( "(1) The overall percent return, 5%, is 3/8 of the way from 4.4% to 6%. (4.4 to 6 is a difference of 1.6; 4.4 to 5 is a difference of .6; .6/1.6 = 6/16 = 3/8). \n" ); document.write( "(2) That means 3/8 of the money should be invested at the higher rate. \n" ); document.write( "ANSWER: 3/8 of $36,000, or $13,500, at 6%; the other $22,500 at 4.4%. \n" ); document.write( "CHECK: .06(13,500)+.044(22,500) = 810+990 = 1800 \n" ); document.write( " |
