Harvey has 12 coins in quarters and dimes, worth $1.80. How many dimes does he have?
\n" ); document.write( "-------------
\n" ); document.write( "Let number of quarters be \"x\"; Value of these is 25x cents.
\n" ); document.write( "Number of dimes is 12-x; Value of these is 10(12-x)=120-10x cents
\n" ); document.write( "------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "value + value = 180 cents
\n" ); document.write( "25x + 120-10x = 180
\n" ); document.write( "15x=60
\n" ); document.write( "x=4 (number of quarters)
\n" ); document.write( "12-x=8 (number of dimes)
\n" ); document.write( "Cheers,
