Explanation:

Step1: Determine daily dose in terms of on - hand tabs

The order is 40 mg per day (po qd means once a day). The on - hand tablets are 20 mg each. Let the number of 20 mg tablets per day be $x$. We set up a proportion: $\frac{40\space mg}{20\space mg}=\frac{x}{1\space tab}$. Solving for $x$, we get $x = \frac{40}{20}\times1= 2$ tabs per day.

Step2: Calculate total tablets for 60 days

If we need 2 tabs per day and the treatment is for 60 days, then the total number of tablets $T$ is $T=2\space tabs/day\times60\space days$.
$T = 120$

Answer:

120
