algebra problem…dont think my answer is right…?
Suppose a patient must take a blood pressure medication that is dispensed in 125-milligram tablets. The dosage is 15 milligrams per kilogram of body weight and is given every 8 hours. If the patient weights 25 kilograms, how many tablets would be needed for a 30-day supply? Use the formula n=24d ÷ [8(b x 15 ÷ 125)], where n is the number of tablets, d is the number of days the supply should last, and b is the body weight of the patient in kilograms.
i keep getting 30 tablets, but that doesnt make sense…

15*25 milligrams per 8 hours i.e. 15*25*3 mg per day, so for 30 days is 15*25*3*30 mg.
but each tablet is 125 mg.
no. of tablets per 30 days is 15*25*3*30/125 = 270
AGREE – the formula is incorrect and gives 30 !
25 kg x 15mg/kg = 375mg = 3 tablets every 8 hours
24 hours in a day, so 8h x 3 = 9, so 9 tablets per day
9 tablets per day x 30 days = 270 tablets
270 TABLETS
