The staff of a school cafeteria makes 94 sandwiches for students on a field trip. if n represents the number of sandwiches eaten by the students, which expression represents the number of remaining sandwiches?
a.n-94
b.94-n
c.94n
d.94+n

Well then have the sandwiches (s) and the students (n).

Well if there are 94 sandwiches, and 30 of them are eaten, we take...

94 - 30 = 64.

Notice how we did that?

s - n

In this case, s=94.

94 - n is the answer.

If this is correct, please leave a thanks and a rating!

f(3) = 12

Step-by-step explanation:

F(x) = 2x2. What is f(3)

f(3) = 2(3) 2

= 6x2

= 12

f(3) = 12
