Question

Before a renovation, a movie theater had 111 seats. After the renovation, the theater has 154 seats. What is the approximate percentage increase of the number of seats in the theater? If necessary, round to the nearest tenth of a percent.

A. 28.1% B. 38.7% C. 43.3% D. 24.8%

Answer 1

Percentage increase will be given by:
(New number-Old number)/(Old number)×100
new number=154 seats
old number =111 seats
thus
Percentage increase is:
(154-111)/111×100
=38.7%

Answer: B. 38.7%
