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?
11 ½ tbsp
9 tbsp
12 tbsp
9 ½ tbsp
The Correct Answer is A
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
