It is common for people to take a dosage of acetaminophen, a pain medication, once per day. The medicine works best when there is a specific amount in the bloodstream. Doctors have found that the amount of acetaminophen, represented as a percentage (%), remaining in a person's bloodstream hours after taking a 1000 milligram dosage can be modeled by the equation:
y = 1000(0.76)*
What does the number 0.76 in this model indicate about the amount of acetaminophen in the bloodstream?
A. It decreases at a rate of 1000% per hour.
B. It decreases at a rate of 76% per hour.
C. It increases at a rate of 24% per hour.
D. It decreases at a rate of 24% per hour.
