I have 23 coins...dimes, nickels, quarters...that equal $2.45. I must have twice the number of nickels as dimes.AS PER YOUR ANSWER THE VALUE IS $2.45..O.K...
\n" ); document.write( "LET DIMES=D
\n" ); document.write( "NICKELS IS TWICE THIS ..THAT = 2D
\n" ); document.write( "HENCE QUARTERS =23-D-2D=23-3D...SINCE TOTAL COINS ARE 23.
\n" ); document.write( "THEIR VALUE IS
\n" ); document.write( "5*2D+10*D+25*(23-3D)=245
\n" ); document.write( "10D+10D+575-75D=245
\n" ); document.write( "55D=330
\n" ); document.write( "D=330/55=6
\n" ); document.write( "HENCE NICKELS ARE 2*6=12...............ITS VALUE = 60
\n" ); document.write( "DIMES ARE 6............................ITS VALUE = 60
\n" ); document.write( "QUARTERS ARE 23-3*6=5..................ITS VALUE = 125
\n" ); document.write( "TOTAL VALUE........................................245...OR..2.45 $
\n" ); document.write( "I know the answer is 12 nickels, 6 dimes and 5 quarters, but I don't know how to write the equation. Thanks in advance for your help.
