<h3>Answer: 7t + 28</h3>

Explanation:

Multiply the outer term 7 by each term inside the parenthesis.

7 times t = 7*t = 7t
7 times 4 = 7*4 = 28

We then add up those results, combining like terms if possible.

That's how we get to 7t + 28

Dr,Goode prescribes 0.2 grams of cold medicine for Donald. This medicine comes in tablets that are 0.5 grams or 0.05 grams. Shou

Using proportions, it is found that Donald should order 4 of the 0.05 gram tablets.

This question is solved by proportions, using a <em>rule of three</em>.

4 tablets are needed, and they should combine for 0.2 grams. How many grams is there going to be on one tablet?

The <em>rule of three</em> is:

1 tablet - x grams

4 tablets - 0.2 grams

Applying cross multiplication:

$4x = 0.2$

$x = \frac{0.2}{4}$

$x = 0.05$

Donald should order 4 of the 0.05 gram tablets.
