A doctor prescribes a medication at a rate of 50 mg/hour. How much will a patient receive in 8 hours?

To determine how much medication the patient will receive in 8 hours at a rate of 50 mg per hour, you need to multiply the hourly dosage by the number of hours.

So, the calculation would look like this:

50 mg/hour * 8 hours = 400 mg.

By performing the multiplication, you find that the total amount of medication administered over the 8-hour period is 400 mg. Thus, the correct answer accurately reflects the total dosage that would be received over that duration.
