The price per share of Envx stock is dropping at a rate of $1.45 each hour what rational number represents the change in the price per share after 5 hours?

Answers

Answer:

-7.25

Step-by-step explanation:

Given,

The stock is dropping at the rate of $1.45 each hour,

So, the change in price of the stock in one hour = - $1.45,

Thus, the total change of the stock in 5 hours

= 5 × change in 1 hour

= 5 × 1.45

= -$ 7.25

∵ A terminating decimal number is always a rational number ( however it is negative )

i.e. the rational number that represents the change in the price per share after 5 hours is -7.25.

Maybe 7.25 because you may have to multiply I am really not sure but hopefully this helps
