Question

If a hospital patient is given 100 milligrams of medicine which leaves the bloodstream at 14% per hour, how many milligrams of medicine will remain in the system after 10 hours? Use the function A(t) = Iert. .

Answer 1

update: 405.52 mg isn't the correct answer

Okay so the right answer is 24.66 because the text says 100 milligrams of medicine which leaves the bloodstream at 14% per hour. so the rate 14% is going to be negative

A(t) = Ie^rt

A(10) = 100e^-0.14(10)

A(10) =24.66
