Answer is C
Let the cost of chartering the plane is X
The per passenger cost be y
When there are 30 passengers chartering the plane cost pee head is.
X/30=Y => X=30Y ---------(1)
If there were 35 passengers, the cost per head would have lessen by 30$.
X/35=(Y-30) => X=35Y-1050 -----(2)
Equating both equations,
30Y = 35Y-1050
5Y=1050
Y=210
The cost of chartering the plane is 30*y => 30*210 => 6300$

from given info we know
x/35 = x/30 - 30
solve for x = $ 6300
OPTION C
