Algebra.Com's Answer #312893 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! There are 23 coins in a bank. All the coins are dimes and quarters. \n" ); document.write( " The total value of the coins is $3.80. \n" ); document.write( " How many dimes are there? \n" ); document.write( " How many quarters \n" ); document.write( ": \n" ); document.write( "We can write two equations here \n" ); document.write( "total coins \n" ); document.write( "d + q = 23 \n" ); document.write( "put this in the form for substitution \n" ); document.write( "d = (23-q) \n" ); document.write( "and value equation \n" ); document.write( ".10d + .25q = 3.80 \n" ); document.write( "now substitute (23-q) for d in the above equation solve for d, then find q \n" ); document.write( " |
