Friends, Brilliantians and members, lend me your ears

Sue knew that there were 300 seats total. She also knew that there were 20 empty seats. To find out how many seats are taken, just subtract the number of empty seats from the total number of seats. 300 - 20 = 280

300-200=? i hope you can solve this....

There were a total of 300 seats, enough to seat 300 people. If there were 20 empty seats, then there must have been $300-20=\boxed{280}$ people in the audience.

It is so simple . Total seats=300. Empty seats=20 Number of people=300-20=280. So there are 280 peoples in the auditorium.

300-20=280.

If there are 300 seats in the auditorium, and all but 20 are filled, that means you have to subtract 300 by 20 to figure out how many people were in the audience. After subtracting, you get your answer as 280. The correct answer is 280.

Subtract the number of seats occupied from the total number of seats in the auditorium

300-20=280

Subtraction

300-20= 280. :D

It's simple. Since there are a total of 300 seats and 20 are empty, 300 - 20 = 280 seats are occupied.

$300-20=280$

This is simple subtraction.

simple is that total seats =300 empty seats=20 how many=? sol: 300-20=280 like a boss.

easy 300 - 20

Total number of seats in the auditorium = 300 Number of vacant seats = 20 Therefore, The number of people in the audience = 300 - 20 = 280

there were 300 seats in the auditorium, and counted 20 empty seats. so, 300 - 20 = 280 peoples

280 peoples at the auditorium

its simple.

300-20=280

300 seats - 20 empty seats = 280 full seats

1.Total = 300, Empty = 20

1. S: = T - E =
2. 300 - 20 = $\boxed{280}$

(300 - 20) = 280
