scoundrel [369]

The amount of medicine in the bloodstream decreases by 25% each hour.

<h3>Exponential equation</h3>

The standard exponential equation is expressed as:

y = ab^x

a is the initial amount

b is the rate

If b < 1, hence there is a declince

Given the expoenentia equation A(h)=600(0.75)^h,

b = 1 - r = 0.75

r = 1 - 0.75

r = 0.25

This shows that the amount of medicine in the bloodstream decreases by 25% each hour.
