a desert outpost has a water supply that is sufficient to last 21 days for 15 people. at the same average rate of water consumption per person , how many days would the water supply last for 9 people?
\n" ); document.write( "----
\n" ); document.write( "# of days and # of people are inversely related:
\n" ); document.write( "d = k/n
\n" ); document.write( "---
\n" ); document.write( "Solve for \"k\" using \"outpost has a water supply that is sufficient to last 21 days for 15 people\"
\n" ); document.write( "21 = k/15
\n" ); document.write( "k = 15*21
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "d = 315/n
\n" ); document.write( "-------------
\n" ); document.write( "Solve \"how many days would the water supply last for 9 people?\"
\n" ); document.write( "d = 315/9
\n" ); document.write( "# of days = 35
