1. Grace has 16 jellybeans in her pocket. She has 8 red ones, 4 green ones and 4 blue ones. What is the minimum number of jellybeans she must take out of her pocket to ensure she has one of each color?
\n" ); document.write( "She might pick 8 red ones, then 4 green ones; the next one she picks will
\n" ); document.write( "result in her having at least one of each color.
\n" ); document.write( "So 8+4+1 picks will guarantee she meets the criteria.
\n" ); document.write( "===============

\n" ); document.write( "2. Sally can paint a house in 4 hours and John can paint the same house in 6 hours. How long will it take for both of them to paint the house together?
\n" ); document.write( "Sally DATA:
\n" ); document.write( "time= 4 hr/job ; rate=(1/4) job/hr
\n" ); document.write( "-------
\n" ); document.write( "John DATA:
\n" ); document.write( "time = 6 hr/job ; rate=(1/6) job/hr
\n" ); document.write( "------------
\n" ); document.write( "Together DATA:
\n" ); document.write( "time = x hr/job ; rate = (1/x) job/hr
\n" ); document.write( "===============
\n" ); document.write( "EQUATION:
\n" ); document.write( "rate + rate = rate together
\n" ); document.write( "1/4 + 1/6 = 1/x
\n" ); document.write( "Multiply thru by 12x to get:
\n" ); document.write( "3x + 2x = 12
\n" ); document.write( "5x=12
\n" ); document.write( "x= 2.4 hrs (Time to do the job together)
\n" ); document.write( "x= 2 hrs and 24 minutes
\n" ); document.write( "Cheers,
