A box of goldfish food can feed 3 fish for 4 weeks. How long will the box last if there are 7 goldfish?
\n" ); document.write( "-----
\n" ); document.write( "time is directly related to # of boxes of food and indirectly related to # of fish
\n" ); document.write( "--------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "t = k*b/f
\n" ); document.write( "----
\n" ); document.write( "Solve for \"k\" using \"A box of goldfish food can feed 3 fish for 4 weeks\".
\n" ); document.write( "4 = k*1/3
\n" ); document.write( "---
\n" ); document.write( "k = 12
\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "t = 12b/f
\n" ); document.write( "---
\n" ); document.write( "How long will the box last if there are 7 goldfish?
\n" ); document.write( "t = 12b/f
\n" ); document.write( "t = 12*1/7
\n" ); document.write( "time = 1.71 weeks
