Answer:
3600 mg of drug per day.
Step-by-step explanation:
We have been given that a patient is ordered 60 mg/kg/day of an antibiotic.
Since the weight of the patient is 60 kg, so the dosage of drug per day would be 60 mg times 60.
Therefore, the patient should receive 3600 mg of drug per day.
Since the patient gets 3 doses per day, so dosage of drug per dosage would be amount of drug per day divided by 3.
Therefore, the amount of drug per dosage would be 1200 mg.
First, write an equation system based on the problem
An equation for "the perimeter of a rectangle is 70 in" can be written as following
∴ 2l + 2w = 70 <em>(first equation)</em>
An equation for "the length is 11 in more than its width" can be written as following
∴ l = w + 11 <em>(second equation)</em>
Second, solve the equation by substitution method o find the dimension of the rectangle.
Substitute/plug l as (w+11) into the first equation
2l + 2w = 70
2(w + 11) + 2w = 70
2w + 22 + 2w = 70
4w + 22 = 70
4w = 70 - 22
4w = 48
w = 48/4
w = 12
The width of the rectangle is 12 in
Substitute w with 12 to the second equation
l = w + 11
l = 12 + 11
l = 23
The length of the rectangle is 23 in
Third, find the area of the rectangle
a = l × w
a = 23 × 12
a = 276
The area of the rectangle is 276 in²
