\"It is possible to have 46 coins consisting of pennies and nickels totaling exactly one dollar. Is she right or wrong? How?
\n" ); document.write( ":
\n" ); document.write( "We can find out by solving it and seeing if we get an integer answer:
\n" ); document.write( ":
\n" ); document.write( "c = no. of pennies; n = no. of nickels
\n" ); document.write( ":
\n" ); document.write( "c + n = 46
\n" ); document.write( ":
\n" ); document.write( ".01c + .05n = 1.00
\n" ); document.write( "Eliminate the decimals, mult by 100, then subtract the 1st equation
\n" ); document.write( "1c + 5n = 100
\n" ); document.write( "1c + 1n = 46
\n" ); document.write( "---------------subtracting eliminates c
\n" ); document.write( "0c + 4n = 54
\n" ); document.write( "n = 54/4
\n" ); document.write( "n = 13.5, therefore the answers is; she's wrong
\n" ); document.write( " \n" ); document.write( "
\n" );
