Roger Roberson · Answer 1

there are 380 seats in total

Step-by-step explanation:

286 + 18 = 304 which is four-fifths of the seat. since 304 seats is 80% of the total seats then if you divide it by 80 then multiply it by 100 you get 380.

so one fifth would be 76 seats and if you multiply it by 4 you get 304 which is four fifths of the seat.
