A group can charter an aircraft at a fixed total cost. If 36 people charter the aircraft rather than 40 people, then the cost per person is greater by $12.
What is the total cost to charter the aircraft?
================================================
Let C = the total cost
Let p = the cost per person if 40 people charter
Since the cost is fixed, we can write the following two equations:
C = 40p
C = 36(p+12)
Solve for p in the 1st and substitute in the 2nd:
C = 36(C/40+12)
Solve for C:
C = (9/10)C + 432
C = $4320
