Before a renovation, a movie theater had 113 seats. After the renovation, the theater has 163 seats. What is the approximate percentage increase of the number of seats in the theater?

A 30.6%

B 49.7%

C 44.2%

D 31%

To solve this problem you can make a rule of three and find the percentage of increase

113 - - - > 100

163 - - - > x

Clearing x we have

x = (163/113) * (100) = 144.25

Then, the percentage of growth is

144.25-100 = 44.25

answer

the approximate percentage increase of the number of seats in the theater 44.25%

C 44.2%
