Answer 1

Answer:

Q10. 21 doses; Q 11. 21 doses; Q12. 42 bottles

Step-by-step explanation:

Question 10

(a) Calculate the total ounces

$\text{Total ounces} = \text{7 da} \times \dfrac{\text{3 times}}{\text{1 da}} = \dfrac{\frac{1}{2}\text{ oz}}{\text{1 time}}= \text{10.5 oz}$

(b) Calculate the number of doses

$\text{Number of doses} = \text{10.5 oz } \times \dfrac{\text{1 dose}}{\frac{1}{2}\text{ oz}} = \textbf{21 doses}$

Question 11

$\text{Number of doses} = \text{7 da} \times \dfrac{\text{3 doses}}{\text{1 da}} = \textbf{21 doses}$

Question 12

(a) Convert ounces to litres

$\text{Volume} = \text{2 oz} \times \dfrac{\text{29.57 mL}}{\text{1 oz}} \times \dfrac{\text{1 L}}{\text{1000 mL}} = \text{0.05914 L}$

(b) Calculate the number of bottles

$\text{No of bottles} = \text{2.5 L} \times \dfrac{\text{1 bottle}}{\text{0.059 14 L}} = \textbf{42 bottles}$
