Answer:
b) The stock is 5.5 less than the original value, and the absolute value is 5.5.
Explanation:
First of all, let's make our number line. The question says you need it to start at -9, so we can assume that it will go until 10. It also wants us to make half-tick marks. (There is an image attached of the number line.)
It says that -5.5 is labeled, so do that on your number line.
Next, it explains that 0 is the original price. 0 is where the stock is starting at. This does not mean that the value of the stock is 0!!! (It means that NO MATTER what the price of the stock is, that is now considered 0.)
Now for the multiple choice, here's why all the answers are incorrect/correct.
a) If something is -5.5 less, it's the same as subtracting a negative number- which makes it positive!! SO this would mean that it added value.
b) Correct! Since it value is lower by 5.5, it's 5.5 less than the og value.
c) Since it's -5.5 greater, that's like adding a negative number: it's the same as subtracting. I suppose this is technically correct, but it's weird.
d) This one says's it's 5.5 greater, which is totally wrong. The value is decreasing, not increasing!
All of them say the absolute value is 5.5. This is correct. Absolute value is the distance from 0, and -5.5 is 5.5 units away from 0. (put simply, absolute value is just making the number positive.
hopefully this makes sense and helps you!!
