Algebra.Com's Answer #765669 by greenestamps(13198)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "The given numbers are probably bad, since the answers are not whole numbers of dollars, or even whole numbers of cents. \n" ); document.write( "Here is a non-algebraic attempt to solve the problem; perhaps another tutor will show an algebraic solution method which also shows the numbers to be bad. \n" ); document.write( "The ratio of the percentages is 5:8. \n" ); document.write( "Since the return from the 5% investment is 2 times the return from the 8% investment, the ratio in which the money is divided between the two investments is 5:16. \n" ); document.write( "So 16/21 of the $36,000 was invested at 5% and 5/21 of it at 8%. \n" ); document.write( "But those are not good answers.... \n" ); document.write( " |
