a coin collection contains nickels dimes and quarters. there are twice as many dimes as quarters and seven more nickels than dimes. the toal value is $3.10. how many quarters are i nthe collection.
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "Let number of quarters be \"x\"; Value of those quarters is 25x cents
\n" ); document.write( "Number of dimes is \"2x\" ; Value of those dimes is 10(2x)=20x cents
\n" ); document.write( "Number of nickels is \"2x+7\" ; Value of those nickels is 5(2x+7)= 10x+35 cents\r
\n" ); document.write( "\n" ); document.write( "EQUATION:
\n" ); document.write( "value + value = value
\n" ); document.write( "25x + 20x + 10x+35 = 310 cents
\n" ); document.write( "55x+35=310
\n" ); document.write( "55x=275
\n" ); document.write( "x=5 (This is number of quarters)
\n" ); document.write( "2x=10 (This is number of dimes)
\n" ); document.write( "2x+7=17 (This is number of nickels)\r
