    On the advice of his physician, a patient purchases a bottle of over-the-counter cough syrup to treat the cough associated with his cold. The bottle contains 16 tablespoons (tbsp) of medication, and 1 dose of the medication is 1 ½ tbsp. After the patient takes 3 doses of the medication, how many tablespoons of medication are left in the bottle?

    Explanation & Rationale

    Calculation: Total volume of medication = 16 tbsp Each dose = 1½ tbsp Total volume in 3 doses 3 doses = 1.5 × 3 = 4.5 tbsp Remaining medication Remaining = 16 – 4.5 = 11.5 tbsp
