(a)
To Calculate: The recommended dosage for a person whose mass is 60 kg
(a)
Answer to Problem 36STP
660 milligrams
Explanation of Solution
Given information: The function rule
Where ‘ m’ represents the person’s body mass and ‘D’ represents the recommended Dosage.
Mass is 60 kg
Calculation: Use the given function rule to find the recommended dosage ‘D’ when mass is 60 kg. Substitute 60 for mass and solve for recommended dosage ‘D’.
Recommended dosage is 660 milligrams when mass is 60 kg
(b)
To Calculate: The recommended dosage for a 200-lb person
(b)
Answer to Problem 36STP
1260 milligrams
Explanation of Solution
Given information: The function rule
Where ‘ m’ represents the person’s body mass and ‘D’ represents the recommended Dosage.
Calculation: First we need to find out the mass for a 200-lb person
One pound is 0.45 kg. To find the mass for a 200 lb person we need to multiply 0.45
Find the recommended dosage for mass of 90 kg. Substitute 90 for mass and solve for recommended dosage ‘D’.
Recommended dosage is 1260 milligrams when mass is 90 kg
