a stock price is 100 it drops to 80 % then the stock further drops to 90%,whats the drop between 80% and 90%

Let's break this down step by step:

1. Initially, the stock price is \( 100 \).
2. The stock drops to 80%. That means the new price becomes:

   \[
   100 \times 0.80 = 80
   \]

3. Now, from this new price of \( 80 \), the stock drops further to 90%. So the new price becomes:

   \[
   80 \times 0.90 = 72
   \]

4. The drop between 80% and 90% is the difference between the two prices:
   
   \[
   80 - 72 = 8
   \]

So, the stock dropped by **8 units** between 80% and 90%.

Here are some related questions to deepen your understanding:

1. What is the total percentage drop from the original stock price of 100 to 72?
2. If the stock rises back to 100% after reaching 72, what will the new price be?
3. What would be the stock price if it dropped to 70% of its initial value?
4. How does compounding affect the price when multiple percentage drops are applied sequentially?
5. What is the percentage drop from 80 to 72?

**Tip:** When dealing with sequential percentage changes, always calculate each step based on the new value rather than the original.
