Answer:
60%
Step-by-step explanation:
we know that
the price per share of a stock decreased from $90 per share to $36 per share
In this problem
$90 represent the 100%
so
using proportion
Find out what percentage represent the difference of ($90-$36)
($90-$36)=$54
Let
x ----> the percentage of the difference

The Answer Would Be 64 because if you divide 8/4.5 its equal to 64/36.
Step-by-step explanation:
4x
__________
| |
x-3| | x-3
| |
|__________
4x
Add all sides together to get perimeter
2(4x)+2(x-3)=10x-6
