a vaccine was purchased by a group of family practice doctors. they purchased 1.5 l of the vaccine. how many patients can be vaccinated if the normal dose is 4 cc?

750 people
7,500 people
3,750 people
375 people

Explanation:

Identify given values and target

We need to find the number of patients.
The total volume purchased is \(1.5\text{ L}\).
The dose per patient is \(4\text{ cc}\).

Convert liters to milliliters

Recall that \(1\text{ L} = 1000\text{ mL}\).

$$ 1.5\text{ L} \times 1000\text{ mL/L} = 1500\text{ mL} $$

Relate milliliters to cubic centimeters

Recall that \(1\text{ mL} = 1\text{ cc}\).

$$ 1500\text{ mL} = 1500\text{ cc} $$

Calculate the number of patients

Divide the total volume by the dose per patient.

$$ \frac{1500\text{ cc}}{4\text{ cc/person}} = 375\text{ people} $$

Answer:

• 750 people
• 7,500 people
• 3,750 people
• 375 people (Correct answer)
