If there were 150seats in the cafeteria and 128 were filled how many seats were left
Subtract.
To find out the number of seats left in the cafeteria, you need to subtract the number of filled seats from the total number of seats.
In this case:
Total number of seats = 150
Number of filled seats = 128
To calculate the number of seats left, you subtract the number of filled seats from the total number of seats:
Number of seats left = Total number of seats - Number of filled seats
Number of seats left = 150 - 128
Now, subtract 128 from 150:
Number of seats left = 22
Therefore, there are 22 seats left in the cafeteria.
