To find the total amount prescribed, you need to multiply the rate of the prescription by the total time for which it is prescribed.

The rate given is 1.5 mg per minute, and the total time is 2 hours. First, convert the hours into minutes:

2 hours x 60 minutes/hour = 120 minutes.

Now, you multiply the prescription rate by the total time in minutes:

1.5 mg/min x 120 minutes = 180 mg.

Thus, the total amount prescribed is 180 mg, which is why this answer is correct.
