: When it was found that 150 more tickets for the choll play were sold than
: the seating capacity of the auditorium. It was decided to have two
: performances. If the total number of tickets sold was equal to the total
: number who attended and if the auditorium was 2/3 full for each of the
: two performances, what is the seating capacity of the auditoruim?
: (A)100
: (B)200
: (C)225
: (D)300
: (E)450
: Ans.E 這題....我完全不知道該怎麼下手...> <
設座位共x 則兩場售票共x+150張 = 兩場加起來人數
每場有2/3滿 所以2/3x + 2/3x = x + 150
4/3x = x + 150
x = 450
