Math Help… PLEASE HELP ME! (Algebra)?
Suppose a patient must take a blood pressure medicine that is dispensed in 125 milligram tablets. The dosage is 15 milligrams per kilogram of body weight and is given every 8 hours. If a patient weighs 25 kilograms, how many tablets would be needed for a 30 day supply?
I was also given this INCORRECT formula to help solve the problem:
n=24d/[8(b*15/125)]
n- number of tablets
d- number of days the supply should last
b- body weight of patient in kilograms

ok, 1 tab = 125 mg.
if they weigh 25 kg, and need 15 mg per kilogram, u multiply 25 x 15 = 375 mg. (per day)
if the tabs are 125 mg.. it takes 3 tabs to make 325 mg.
so multiply 3 125 mg tabs x 30 days = 90 125 mg tabs (3 per day)
n = ((15mg * b) * 3d) / 125
((15mg * 25kg/1kg) * 90) / 125
