The cost to charter a certain airplane is x dollars. If the 25 members of a club chartered the plane and shared the cost equally, what was the cost per member?
(1) If there had been 5 more members and all 30 had shared the cost equally, the cost per member would have been $40 less.
(2) The cost per member was 10 percent less than the cost per person on a regularly scheduled flight.

Kudos for a correct solution.
here we have to calculate the value of x
st.1
\(\frac{x}{25} - \frac{x}{30}\) \(=40\)
\(x\frac{(6-5)}{150}=40\)
\(x=6000\)
hence sufficient
st.2 since we don't know the cost of regular scheduled flight. hence st.2 alone is insufficient to answer the question.
hence A

Statement 1 means that(x/30)=((x/25)-40). Hence we can find x
Statement 2 gives no additional information to find cost per person on regular flight. Hence answer A
