Katie has $880 in five- and twenty-dollar bills. If she has four more twenties than fives, how many 20-dollar bills does she have?
\n" ); document.write( "------------------------
\n" ); document.write( "Let # of fives be \"f\"; Let # of twenties be \"t\".
\n" ); document.write( "Equations:
\n" ); document.write( "Value Eq: 5f + 20t = 880
\n" ); document.write( "Quantity Eq: t = f+4
\n" ); document.write( "--------------------------------
\n" ); document.write( "Substitute and solve for f and then for t.
