Answer:
50.3%
Explanation:
1) Lets find the number of new seats: (227 - 151) = 76 new seats. Percent increase is defined as:
(New Seats)/(Initial Seats) = (76/151) = 0.503 or 50.3% (to the nearest twnth of a percent)
Check:
Would a 50.3% increase from 151 add 57 seats?
(151)*(0.503) = 76 new seats YES
