Answer:
An equation that represents the given situation is
and the additional number of students that can be seated is 47
Explanation:
Number of students already seated in school cafeteria = 203
Let x be the additional number of students that can be seated
So, Total number of seats available in school cafeteria = 203+x
We are given that the school cafeteria seats 250 students
So, 203+x=250
Hence an equation that represents the given situation is
and the additional number of students that can be seated is 47
