Answer:
7.25 hours
Step-by-step explanation:
Given the price per share of envx stock is dropping at a rate of $1.45 each hour.
which means for every hour the decrease in the price per share is $1.45
After 5 hours
1 hour------> $1.45
5 hour------->x
on cross multiplication we get
x=5*1.45=$7.25
therefore there is a $7.25 change in the price of the share after 5 hours
