Question

an elevation on the tenth floor goes down 9 floors then it goes up 19 floors down three and finally down 12 what floor does it end up on write an equation to show how you found your answer

Answer 1

onIn order to solve this, we have to add the number of floors the elevator goes up and subtract the number of floors the elevator goes down, like this:

Initially, it goes down 9 floors since it was at the 10th floor we get:

10 - 9 = 1

Then, after it goes down 9 floors it gets to the first floor, then it goes up 19 floors , now we get:

1 + 19 = 20

After it goes up to the 19th floor from the fits one, it gets to the 20th floor, then it goes down 3 floors, now we get:

20 - 3 = 17

After it goes down 3 floors it gets to the 17th floor, then it goes 12 floors down from the 17th floor:

17 - 12 = 15

At the end, the elevator ends up in the 15th floor
