Sure! Let’s solve each of these
Integer Word Problems step by step.

Problem 1:
> How cold will it get if it is 7°C outside and the temperature drops by 19°C in the next six hours?
Solution:
We start at
+7°C and the temperature
drops by
19°C, which means we subtract 19 from 7.
> 7 - 19 = -12
✔ Answer: -12°C

Problem 2:
> Cara has $4,000 in her bank account. She spends $1,000 for her admission and $200 for buying accessories. How much money is left with her?
Solution:
Start with $4,000.
Subtract the two expenses:
> 4,000 - 1,000 = 3,000
> 3,000 - 200 = 2,800
✔ Answer: $2,800

Problem 3:
> Suppose your office elevator was initially on the 12th floor. It goes down 11 floors and then goes up 5 floors. Find on which floor one can find the elevator.
Solution:
Start at
12th floor.
- Goes
down 11 floors: 12 - 11 =
1st floor
- Then goes
up 5 floors: 1 + 5 =
6th floor
✔ Answer: 6th floor

Problem 4:
> Mr. Roberts makes 4 withdrawals of $10 each. How much has he withdrawn in total?
Solution:
Each withdrawal is $10, and he does this 4 times.
> 4 × 10 = 40
Since it’s a withdrawal (money leaving his account), we can think of it as negative, but the question asks “how much has he withdrawn in total?” — meaning the
total amount withdrawn, which is a positive value.
✔ Answer: $40
*(Note: If the problem asked for his account change, it would be -$40. But here, it’s asking for total amount withdrawn — so $40.)*

Problem 5:
> A number added to 5 is equal to -11. Find the number.
Solution:
Let the unknown number be
x.
We are told:
> x + 5 = -11
To solve for x, subtract 5 from both sides:
> x = -11 - 5
> x = -16
✔ Answer: -16
