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? --------------------------------- Let the fixed cost be "x" dollars ------------------- 1st average cost: x/40 dollars -------------- 2nd average cost; x/36 dollars ---------------- EQUATION: 36 person cost - 40 person cost = 12 dollars x/36 - x/40 = 12 (40x-36x) = 12*36*40 4x = 12*36*40 x = 3*36*40 x = \$4320 x/40 = \$108 (average cost for 40 persons) ==================== Cheers, Stan H.
