Mathematics

$\large \boxed{\text{1. 24 doses; 2. 4614 mL}}$

Step-by-step explanation:

1. Prescription

(a) Calculate the volume of the mouthwash

Tetracycline 0 mL (it's a solid)

Nystatin 40

Diphenhydramine 60

Dexamethasone 140

TOTAL 240 mL

(b) Calculate the number of doses

1 tsp = 5 mL, so a dose of

2 tsp = 10 mL

$\text{No. of doses} = \text{240 mL} \times \dfrac{\text{1 dose}}{\text{10 mL}} = \text{24 doses}\\\\\text{There are $\large \boxed{\textbf{24 doses}}$ in the prescription.}$

2. Punch

You must convert gallons, pints, and cups to millilitres.

The conversion factors are

1 US gal = 3785 mL

1 US pt = 473 mL

1 US c = 237 mL

(a) Gallons to millilitres

$\text{No. of millilitres} = \frac{3}{4}\text{ gal} \times \dfrac{\text{3785 mL}}{\text{1 gal}} = \text{2839 mL}$

(b) Pints to millilitres

$\text{No. of millilitres } = \text{3 pt} \times \dfrac{\text{473 mL}}{\text{1 pt}} = \text{1419 mL }$

$\text{No. of millilitres} = \text{1.5 c } \times \dfrac{\text{237 mL}}{\text{1 c}} = \text{356 mL}$

(d) Volume of punch

Orange juice = ¾ gal = 2839 mL

Ginger ale = 3 pt = 1419

Pineapple juice = 1½ c = 356

TOTAL = 4614 mL

$\text{The final volume of the punch is $\large \boxed{\textbf{4614 mL}}$}$
