Let's solve this step-by-step.
1. Determine the amount of expectorant per tablespoon:
- The given amount of expectorant per tablespoon is [tex]\( 25 \)[/tex] mg.
2. Determine the number of tablespoons in a quart:
- We know that there are [tex]\( 64 \)[/tex] tablespoons in a quart.
3. Calculate the total amount of expectorant in a quart:
- To find the total amount of expectorant, you need to multiply the amount of expectorant per tablespoon by the number of tablespoons in a quart:
[tex]\[
\text{Total expectorant} = \text{Amount per tablespoon} \times \text{Number of tablespoons in a quart}
\][/tex]
- Substituting the given values:
[tex]\[
\text{Total expectorant} = 25 \, \text{mg} \times 64 \, \text{tbsp}
\][/tex]
4. Calculate the result:
- Performing the multiplication:
[tex]\[
25 \, \text{mg} \times 64 \, \text{tbsp} = 1600 \, \text{mg}
\][/tex]
Therefore, the total amount of expectorant in a quart of this medication is [tex]\( 1600 \)[/tex] mg.
The correct answer is:
#### 1600 mg
