b.
Capsule form is the most expensive.
c.
Caplet form is the most expensive.
d.
The forms all have the same unit price.

Answer 1

To determine which form is the most expensive, we need to calculate the cost per milligram for each form.

1. **Tablet Form**:
- Dose: 50 mg
- Cost: $75.00 for 100 tablets
- Total mg in the bottle: \( 100 \text{ tablets} \times 50 \text{ mg/tablet} = 5000 \text{ mg} \)
- Cost per mg: \( \frac{75.00}{5000} = 0.015 \) dollars/mg

2. **Capsule Form**:
- Dose: 75 mg
- Cost: $63.75 for 85 capsules
- Total mg in the bottle: \( 85 \text{ capsules} \times 75 \text{ mg/capsule} = 6375 \text{ mg} \)
- Cost per mg: \( \frac{63.75}{6375} = 0.01 \) dollars/mg

3. **Caplet Form**:
- Dose: 100 mg
- Cost: $70.00 for 40 caplets
- Total mg in the bottle: \( 40 \text{ caplets} \times 100 \text{ mg/caplet} = 4000 \text{ mg} \)
- Cost per mg: \( \frac{70.00}{4000} = 0.0175 \) dollars/mg

Now we can compare the cost per milligram for each form:

- Tablet Form: 0.015 dollars/mg
- Capsule Form: 0.01 dollars/mg
- Caplet Form: 0.0175 dollars/mg

Among these, the **Caplet Form** is the most expensive at **0.0175 dollars/mg**.

So the answer is:
c. Caplet form is the most expensive.
