Algebra.Com's Answer #136906 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! This is from a book. Marta has $6000 to invest. She puts X dollars of this money into a savings account that earns 3% per year, and with the rest, she buys a certificate of deposit that earns 6% per year. Write an equation for the total amount of money T Marta will have after one year. \n" ); document.write( "I tried this. \n" ); document.write( "T = 6000X (3%) + (6000- 180x)(6%) \n" ); document.write( "6000X (.03) \n" ); document.write( "180X + (360-10.8X) \n" ); document.write( ": \n" ); document.write( "when you multiply x by 6000......your muliplying by the portion of 6000 dollars that is invested at 3%. Let try this another way \n" ); document.write( ": \n" ); document.write( "lets call x the amount she put into the savings at 3% \n" ); document.write( "lets call y the amount she put into cd at 6% \n" ); document.write( ": \n" ); document.write( "we know that x+y=6000 therefore we know that y=6000-x \n" ); document.write( ": \n" ); document.write( "total amount after 1 year lets call t \n" ); document.write( ": \n" ); document.write( "T=6000+.03x+.06y \n" ); document.write( ": \n" ); document.write( "T=6000+(.03x+.06(6000-x)) \n" ); document.write( ": \n" ); document.write( "T=6000+.03x+360-.06x \n" ); document.write( ": \n" ); document.write( "T=6360-.03x \n" ); document.write( " |
