Soon after taking an aspirin a patient has absorbed 300mg of the drug. if the amount of aspirin decays exponentially, with 150g remaining after 2hours:

a). determine an exponential function of the form y=a(b t)

that can be used to model the absorption of aspirin in the blood stream after t hours, in the above scenario.

b). using the model obtained in part (a) how much aspirin will be in the blood after 5.5 hrs.

c). using the model obtained in a) find to the nearest 0.1, the time it will take for the amount of aspirin in the bloodstream to decrease to 10mg?
