Warren has 40 coins (all nickels, dimes, and quarters)worth $4.05. He has 7 more nickels than dimes. How many quarters does Warren have?
\n" ); document.write( "-----------
\n" ); document.write( "Let number of dimes be \"x\" ; Value of those dimes is 10x cents.
\n" ); document.write( "Number of nickels is \"x+7\" ; Value of those nickels is 5(x+7)=5x+35 cents
\n" ); document.write( "Number of quarters is \"40-2x-7\"=\"33-2x\";Value of those is 25(33-2x)=825-50x
\n" ); document.write( "EQUATION:
\n" ); document.write( "value + value + value = 405 cents
\n" ); document.write( "10x+5x+35+825-50x=405
\n" ); document.write( "-35x=-420
\n" ); document.write( "x=12 (#of dimes)
\n" ); document.write( "33-2x=33-24=9 (# of quarters).
\n" ); document.write( "Cheers,
