A 30.6%
B 49.7%
C 44.2%
D 31%

Answer 1

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%
