Question

A doctor is administrating medicine to a patient and needs to adjust the dosage based on the patients weight. The number of teaspoons of medicine t that a person of a certain weight w, in pounds, should take is approximated by the equation t=3+0.05w. Which of the following is the appropriate dosage of medicine, in ounces, for the doctor to administer to a 180 lb person?

Answer 1

Answer: The appropriate dosage of medicine for a 180 Ib person is 12 ounces.

Explanation:

From the word problem, we know that:

• t = number of teaspoons of medicine
• w = the weight of the person
• equation: t= 3 + 0.05w
• The person weighs 180 lb

Since we are given w (the amount the person weighs is 180 Ib), we can plug the value into the equation to solve for t.

t= 3 + 0.05 (180)

t = 3 + 9

t = 12

So the appropriate dosage of medicine for a 180 Ib person is 12 ounces.
