Mutt is half as old as Jeff will be when Mutt is twice as old as Jeff was when Mutt was half as old as Jeff is now. In five years, the sum of Mutt’s and Jeff’s ages will be 100. How old are Mutt and Jeff now?
\n" ); document.write( ":
\n" ); document.write( "I think the 1st sentence just means \"Mutt is half as old as Jeff\"
\n" ); document.write( ":
\n" ); document.write( "M = .5J
\n" ); document.write( ":
\n" ); document.write( "The sentence \"In five years, the sum of Mutt’s and Jeff’s ages will be 100.\":
\n" ); document.write( "(M + 5) + (J + 5) = 100
\n" ); document.write( "M + J + 10 = 100
\n" ); document.write( "M + J = 100 -10
\n" ); document.write( "M + J = 90
\n" ); document.write( "Substitute .5J for M
\n" ); document.write( ".5J + J = 90
\n" ); document.write( "1.5J = 90
\n" ); document.write( "1.5J = 90/1.5
\n" ); document.write( "J = 60 years
\n" ); document.write( "Then:
\n" ); document.write( "M = 30 years old \n" ); document.write( "
\n" );
