-------------
That depends on what "A" means.
-------------------
(a) A=30(0.2)^t

A=30(.2)^T LET T=2
A=30(.2)^2=30*.04=1.2
A=30(.4)^2=30*.16=4.8
A=30(12)^2=30*144=4320
A=30(14)^2=30*196=5,880
IF THE SMALLER THE "A" FACTOR, THE FASTER THE MEDICATION IS ABSOLVED THEN THE FIRST TEST (a) IS THE FASTEST.
