You can put this solution on YOUR website!
Let the number of $1 bills = x, so then number of $10 bills is 51-x.
\n" ); document.write( "From the problem description, you can write:
\n" ); document.write( "x($1)+(51-x)($10) = $213 Simplify and solve for x.
\n" ); document.write( "x+510-10x = 213
\n" ); document.write( "-9x+510 = 213 Add 510 to both sides.
\n" ); document.write( "-9x = -297 Divide both sides by -9
\n" ); document.write( "x = 33 and 51-x = 51-33 = 18.
\n" ); document.write( "The motel clerk has 33 $1 bills and 18 $10 bills.
\n" ); document.write( "
\n" );
