Question #c5e26

Answer 1

`"2 tablets"`

Explanation:

The first thing to do here is to figure out how many milligrams you need to administer per dose.

Since you know that the total dose amounts to `"160 mg"` and that you need to divide this into `4` doses, you can say that each dose will have

`1 color(red)(cancel(color(black)("dose"))) * "160 mg"/(4color(red)(cancel(color(black)("doses")))) = "40 mg"`

So each dose must have `"20 mg"` of this drug. Since you know that each tablet has `"20 mg"`, you can say that each dose will need

`40 color(red)(cancel(color(black)("mg"))) * "1 tablet"/(20color(red)(cancel(color(black)("mg")))) = color(darkgreen)(ul(color(black)("2 tablets")))`

Therefore, you can administer `"160 mg"` of this drug in `4` doses by using `2` `"20-mg"` tablets per dose.
