<h2>Answer:</h2>

She can assemble 20 boxes.

<h2>Step-by-step explanation:</h2>

1. Create a table

<u># of Boxes</u>                    <u>Time</u>

4                        =>        5 min

<em>x</em>                        =>       25 min

2. Use the table to cross multiply.

5 · <em>x</em> = 4 · 25

5<em>x</em> = 100

5<em>x</em>/5 = 100/5

<em>x</em> = 20
