Question

On opening night of the school play, 220 seats in the auditorium were occupied. The auditoriumiseats 400 people. What percent of the seats were unoccupied? A 40% B 45% C 55% D 60%

Answer 1

Answer:

B. 45%

Explanation:

The total number of seats in the auditorium = 400

Number of occupied seats = 220

Thus, the number of unoccupied seats = 400-220 = 180

So, the percentage of seats that were unoccupied will be:

$\begin{gathered} =\frac{180}{400}\times100 \\ =\frac{180}{4}\% \\ =45\% \end{gathered}$

The correct choice is B.
