MissTica

Answer:

She will get 80mg of dextromethorphan and 800mg of guaifenesin. And the bottle last for 6 days approximately.

Step-by-step explanation:

Given that the Robitussin DM contains dextromethorphan 10mg/5mL and gualfenesin 100mg/5mL. And we are also given that Mrs Smith took four doses and each dose is 2 teaspoons=2X5=10mL.

So, four doses=4X10=40mL.

So, dextromethorphan in 4 doses is = $\frac{10}{5}X40=80mg$

And Guaifenesin in 4 doses is = $\frac{100}{5}X40=800mg$

Dosage of medicine daily she has to take=40mL and the bottle contains 237 mL. Hence the number of days bottle last = $\frac{237}{40}=5.925$ ≈6 days approximately.
