**The concentration of medication in a patient's blood
decreases by 8% every hour. If the initial concentration
when the dose is given is 0.15 milligrams of medication
per 100 milliliters of blood, which equation represents
the concentration per 100 milliliters of blood after t
hours have passed?
A. C= 0.15(0.92)¹-1
C. C= 0.15(-0.08)-1
B. C = 0.15(1.08)¹-¹
D. C = 0.15-0.92(t-1)
