The percentage of drug released in the bloodstream t hours after being administered is affected by numerous variables including drug solubility and filler ingredients. For a particular drug and dosage, the percentage of drug released P is given by P = 48 t 1 / 5 ( 0 ≤ t ≤ 35 ) . For example, the value P = 50 represents 50% of the drug released. a. Determine the percentage of drug released after 2 hr. Round to the nearest tenth of an hour. b . How many hours is required for 75% of the drug to be released? Round to the nearest tenth of an hour.
