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.
