Neil has a total of twelve $5 and $10 bills in his wallet.He has 5 times as many $10 bills as $5 dollar bills. How many of each does he have?
\n" ); document.write( ".
\n" ); document.write( "Let x = number of $5 bills
\n" ); document.write( "then from \"Neil has a total of twelve\" we have
\n" ); document.write( "12-x = number of $10 bills
\n" ); document.write( ".
\n" ); document.write( "From: \"He has 5 times as many $10 bills as $5 dollar bills.\" we get our equation:
\n" ); document.write( "x = (1/5)(12-x)
\n" ); document.write( "multiplying both sides by 5:
\n" ); document.write( "5x = 12-x
\n" ); document.write( "6x = 12
\n" ); document.write( "x = 2 (number of $5 bills)
\n" ); document.write( ".
\n" ); document.write( "Number of $10 bills:
\n" ); document.write( "12-x = 12-2 = 10
\n" ); document.write( " \n" ); document.write( "
\n" );
