Question

A patient must take 1000mg of a prescription medication three times a day.

a.)How many 500mg tablets are required to fill a month prescription?

b.) If the cost of a tablet is 17 cents, how much will the patient have to pay for the prescription?

Answer 1

# mg needed per month: (30 days/1)*(3 doses/1 day)*(1000 mg/1 dose)= 90, 000 mg

 

# tablets needed: (90,000mg/1)*(1 tablet/500 mg)=180 tablets.

 

cost of tablets=(180 tablets/1)*($0.17/1 tablet)=$30.60
