A stock rises in value from $20 to $40. Then it decreases in value from $40 to $20. Is the percentage increase from $20 to $40 the same as the percentage decrease from $40 to $20? Explain.

Answer:

No

Explanation:

To find how much something is a percent of another number, divide it by said other number

20/40 = 0.5

0.5 × 100 = 50%

The first one is a 50% increase

Then, 40/20 = 2

2 × 100 = 200%

It is a 200% decrease

So no, because 50% doesn't equal 200%
