Answer:

The integer would -3.

Step-by-step explanation:

Think of it this way:

The elevator goes +7 (Positive = Up) and then -4  (Negative = Down). What is 7-4? That's easy it's just 3. But since the floor level goes down, it would be negative. So you just make it -3.

Check your work:

If we went up from the 4th floor by three, we would get up to the 7th floor.

Hope it Helps!
