Question

1. formulate a plan an elevator began on the 4th floor of a building. from there the elevator traveled 8 floors up, then 3 floors down, then 4 floors down, then 1 floor up. on what floor did the elevator stop?

Explanation:

Step1: Start with initial floor

The elevator starts on the 4th floor, so we begin with \( 4 \).

Step2: Add floors traveled up

It travels 8 floors up, so we add 8: \( 4 + 8 = 12 \).

Step3: Subtract floors traveled down (first time)

Then it goes 3 floors down, so subtract 3: \( 12 - 3 = 9 \).

Step4: Subtract floors traveled down (second time)

Next, it goes 4 floors down, so subtract 4: \( 9 - 4 = 5 \).

Step5: Add floors traveled up (second time)

Finally, it goes 1 floor up, so add 1: \( 5 + 1 = 6 \).

Answer:

The elevator stopped on the 6th floor.
