document.write( "Ex: A motel clerk counts his $1 and $10 bills at the end of the day. He finds that he has a total of 74 bills having a combined monetary value of $326. Find the number of bills of each denomination that he has.
\n" );
document.write( "let x= the number of $1 bills the clerk has, and y= the number of $10 bills he has
\n" );
document.write( "He has 74 bills altogether, so one equation is x+y=74. To find the second equation, the dollar amount in $1 bills plus the dollar amount in $10 bills is $326, so 1x+10y=326. \n" );
