A woman has 25 coins in her pocket, all of which are dimes and quarters.
\n" ); document.write( " If the total value of the coins is $ 4.75,
\n" ); document.write( " how many dimes and how many quarters does she have?
\n" ); document.write( ":
\n" ); document.write( "d = no. of dimes
\n" ); document.write( "q = no. of quarters
\n" ); document.write( ":
\n" ); document.write( "\"A woman has 25 coins in her pocket, all of which are dimes and quarters.\"
\n" ); document.write( "d + q = 25
\n" ); document.write( "\"If the total value of the coins is $ 4.75,\"
\n" ); document.write( ".10d + .25q = 4.75
\n" ); document.write( ":
\n" ); document.write( "how many dimes and how many quarters does she have?
\n" ); document.write( " multiply above equation by 10, subtract the first equation
\n" ); document.write( "d + 2.5q = 47.5
\n" ); document.write( "d + q = 25
\n" ); document.write( "-----------------subtraction eliminates d, find q
\n" ); document.write( "0 + 1.5q = 22.5
\n" ); document.write( "q = 22.5/1.5
\n" ); document.write( "q = 15 quarters
\n" ); document.write( "then
\n" ); document.write( "25 - 15 = 10 dimes
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check
\n" ); document.write( "15 * .25 = 3.75
\n" ); document.write( "10 * .10 = 1.00
\n" ); document.write( "----------------
\n" ); document.write( "totals to 4.75
\n" ); document.write( "
\n" ); document.write( "
\n" );
