A group can charter an aircraft at a fixed total cost. If 36 ppl charter the aircraft rather than 40, then the cost per person is greater by $12. What is the cost per person if 40 people charter the aircraft?
\n" ); document.write( "---------------------------------
\n" ); document.write( "Let the fixed cost be \"x\" dollars
\n" ); document.write( "-------------------
\n" ); document.write( "1st average cost: x/40 dollars
\n" ); document.write( "--------------
\n" ); document.write( "2nd average cost; x/36 dollars
\n" ); document.write( "----------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "36 person cost - 40 person cost = 12 dollars
\n" ); document.write( "x/36 - x/40 = 12
\n" ); document.write( "(40x-36x) = 12*36*40
\n" ); document.write( "4x = 12*36*40
\n" ); document.write( "x = 3*36*40
\n" ); document.write( "x = $4320
\n" ); document.write( "x/40 = $108 (average cost for 40 persons)
\n" ); document.write( "====================
