3/4a cow eats 7 bags of feed in 9 days.how long will 12 cow take to eat the 7 bags
\n" ); document.write( "-----
\n" ); document.write( "t is inversely propotional to # of cows and directly proportional to # of bags.
\n" ); document.write( "---------------------
\n" ); document.write( "t = k*b/c
\n" ); document.write( "----
\n" ); document.write( "Solve for \"k\" using \"a cow eats 7 bags in 9 days\"::
\n" ); document.write( "9 = k*7/1
\n" ); document.write( "k = 9/7
\n" ); document.write( "------
\n" ); document.write( "Equation::
\n" ); document.write( "t = (9/7)b/c
\n" ); document.write( "-------------------------
\n" ); document.write( "How long will 12 cow take to eat the 7 bags
\n" ); document.write( "t = (9/7)7/12
\n" ); document.write( "---
\n" ); document.write( "t = 9/12 = 3/4 of a day
