You can put this solution on YOUR website!
you have total of 50 coins in your pocket.you only quarters and dimes and the total value $ is 11.00
\n" ); document.write( " how many of each coin do you have \r
\n" ); document.write( "\n" ); document.write( "You have the equations mixed up
\n" ); document.write( ":
\n" ); document.write( "Total coin equation
\n" ); document.write( "q + d = 50
\n" ); document.write( "or
\n" ); document.write( "d = (50-q); use this for substitution
\n" ); document.write( ":
\n" ); document.write( "and
\n" ); document.write( "total value equation
\n" ); document.write( ".25q + .10d = 11.00
\n" ); document.write( ":
\n" ); document.write( "Substitute (50-q) for d, find q
\n" ); document.write( ".25q + .10(50-q) = 11
\n" ); document.write( ":
\n" ); document.write( ".25q + 5 - .10q = 11
\n" ); document.write( ":
\n" ); document.write( ".25q - .10d = 11 - 5
\n" ); document.write( ";
\n" ); document.write( ".15q = 6
\n" ); document.write( "q = \"6%2F.15\"
\n" ); document.write( "q = 40 quarters
\n" ); document.write( "then
\n" ); document.write( "50 - 40 = 10 dimes
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the total value equation
\n" ); document.write( ".25(40) + .10(10) =
\n" ); document.write( "10 + 1 = 11
\n" ); document.write( " \n" ); document.write( "
\n" );
