Answer:
9 ml
Step-by-step explanation:
The Pediatrician prescribes 5 milliliters of cough syrup for every 25 lb of child weight.
Now, the weight of Jocelyn is 45 lb.
If the rate of prescribing the cough syrup in ml per weight of patients remains constant,
Then we can use the unitary method to get the amount of cough syrup prescribed by the Pediatrician for Jocelyn, and that will be
[tex]\frac{5*45}{25} =9[/tex] ml. (Answer)
The amount of cough syrup the doctor will prescribe for Jocelyn who weighs 45lb is 9ml.
It is given that:
Pediatricians prescribe 5mL of cough syrup for every 25lb of a child's weight
By the unitary method, for a child has a weight of 1 lb Pediatrician will prescribe = 5/25 = 1/5ml of cough syrup
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
So, the amount of cough syrup the doctor will prescribe for Jocelyn who weighs 45lb will be 45*1/5 = 9 ml.
Therefore, the amount of cough syrup the doctor will prescribe for Jocelyn who weighs 45lb is 9ml.
