15 mg in the morning; 10 mg at bedtime; 25 mg total

Explanation:

Calculate the morning dose

Using the Dosage Calculations knowledge point

$$ \text{Morning Dose} = 1.5 \text{ tablets} \times 10 \text{ mg/tablet} = 15 \text{ mg} $$

Calculate the bedtime dose

Using the Dosage Calculations knowledge point

$$ \text{Bedtime Dose} = 1 \text{ tablet} \times 10 \text{ mg/tablet} = 10 \text{ mg} $$
