Explanation:

30.

Step1: Assume dosage per dose

Let's assume each dose is \(x\) mL. But since not given otherwise, if we assume a standard - common sense dose of cough medicine, we often consider 10 mL per dose.

Step2: Calculate total mL for 6 doses

Total mL = Dose per dose×Number of doses. So, \(10\times6 = 60\) mL.

Step1: Know the conversion factor

1 fluid - ounce is approximately 29.5735 mL.

Step2: Calculate ounces

We know from 30 that total mL is 60 mL. So, number of ounces \(n=\frac{60}{29.5735}\approx2.03\) ounces.

Step1: Use the conversion

1 tablespoon is approximately 14.7868 mL.

Answer:

60 mL
