a clerk counts $1.00 and $10.00 bills at the end of the day he finds he has a total of 49 bills having a combined monetary value of $139 . find the number of bills of each denomination\r
\n" ); document.write( "\n" ); document.write( "Let x = the number of $1.00 bills
\n" ); document.write( " 49-x = the number of $10.00 bills\r
\n" ); document.write( "\n" ); document.write( "1.00x + 10.00(49-x) = 139
\n" ); document.write( " x + 490 -10x = 139\r
\n" ); document.write( "\n" ); document.write( "Combine like terms
\n" ); document.write( " -9x = 139-490
\n" ); document.write( " x = -351/-9
\n" ); document.write( " x = 39\r
\n" ); document.write( "\n" ); document.write( " 49-x = 10\r
\n" ); document.write( "\n" ); document.write( "The clerk has 39 $1 bills and 10 $10 bills\r
\n" ); document.write( "
\n" ); document.write( "
