Answer:
[tex]\large \boxed{\text{Eight days}}[/tex]
Step-by-step explanation:
1.Convert all volumes to millilitres
(a) Chlorpheniramine
V = 100 mL
(b) Lidocaine
[tex]V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \text{59 mL}[/tex]
(c) Banana flavouring
[tex]V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \text{2.5 mL }[/tex]
2. Calculate the total volume
Chlorpheniramine = 100 mL
Lidocaine = 59
Banana flavouring = 2.5
TOTAL = 162 mL
3. Calculate the number of doses
[tex]\text{Doses} = \text{162 mL} \times \dfrac{\text{1 dose}}{\text{10 mL}} = \text{16.2 doses}[/tex]
4. Calculate the number of days
[tex]\text{Days} = \text{16.2 doses } \times \dfrac{\text{1 da}}{\text{2 doses}} = \textbf{8 da}\\\\\text{The solution will last for $\large \boxed{\textbf{eight days}}$}[/tex]
