Hello there!

In the morning there were s students in the library. In the afternoon, there were 4 fewer students in the library than there were in the morning. Write an expression for the number of students in the afternoon.

4 fewer means -4.

S - 4 is the expression that is equivalent to the amount of students who were in the library in the afternoon.

I hope this helps!
