Researchers are testing a new type of antibiotic. After administering a dose to a patient, they estimate that the amount of antibiotic in the patient's bloodstream will decrease by 26% every hour. If there are x milligrams of antibiotic in a patient's bloodstream after 2 hours, about how much will there be after 4 hours?
a) 0.74^3 times x
b) 0.74^2 times x
c) 1.26x
d) 1.26^3 times x
e) 1.26^3 times x
f) 0.74x
g) 1.26^2 times x
b) 0.74^2 times x
After 2 hours: 0.74^2 * x = 0.5476x
After 4 hours: 0.74^4 * x = 0.304024576x
So, after 4 hours, there will be approximately 0.304x milligrams of antibiotic in the patient's bloodstream.
