SUMMARY

The discussion centers on the "factor label method," a technique used for unit conversion in mathematical problems. Participants emphasize the importance of understanding the method before attempting to solve related problems, particularly in contexts like calculating charges between companies. Additionally, they highlight the necessity of consulting experts when dealing with real-life applications, such as determining correct medication dosages, as mathematical calculations alone may not suffice. This conversation underscores the method's relevance in both academic and practical scenarios.

Homework Statement
1 .You want to have a 30 m2 room in your house retiled. A company called Wasta Tiles will do it for $50
per m2
. Another company, Zaki Floors, will do it for $4 per ft2
. Which company has the lower price?
Justify your answer using the factor label method. 1 m2 = 10.8 ft2



2. A patient needs 0.50 mg of a certain drug per 10.0 pounds of body weight. Each pill contains 4.00 mg of
the drug. If the patient weighs 73.0 kg, how many pills should the patient be given? (1 kg weighs 2.2
pounds). Use the factor label method
Relevant Equations
1 kg weighs 2.2 pounds

For 1: Money charged by one company is already given. Calculating the charges by the other company (while keeping the unit in mind) will solve the problem.

For 2: Consult an expert! Only Mathematics is not sufficient to know the correct dosage of a medicine!
