Answer 1

To find out how many days it will take Milly to sell 56 boxes of Girl Scout cookies, we can set up a proportion based on her sales rate.

Milly's selling rate is:
- 8 boxes in 3 days.

We want to find out how many days (let's call it \( x \)) it will take her to sell 56 boxes. We can set up the proportion as follows:

\[
\frac{8 \text{ boxes}}{3 \text{ days}} = \frac{56 \text{ boxes}}{x \text{ days}}
\]

Now, we can cross-multiply and solve for \( x \):

\[
8x = 56 \cdot 3
\]

Calculating \( 56 \cdot 3 \):

\[
56 \cdot 3 = 168
\]

So we have:

\[
8x = 168
\]

Now divide both sides by 8:

\[
x = \frac{168}{8} = 21
\]

Thus, it will take Milly **21 days** to sell 56 boxes.

**Response: 21 days**
