Question

If you have $20, then you spend $10, which direction would the point representing the money you have remaining move on a horizontal number line?
1.downward
2.upward
3.to the left
4.to the right

Answer 1

On a horizontal number line, if you start at $20 and then spend $10, your remaining amount is $10. In terms of direction on the number line, spending money would move you to the left, as you are decreasing the amount of money you have.

So the correct answer is:
**3. to the left**.
