Answer:
In 14 weeks will they have the same number of good behavior stars
Step-by-step explanation:
Let
x ----> the number of weeks
y ----> the number of good behavior stars
we know that
<em>Alice</em>
----> equation A
<em>Mack</em>
----> equation B
To find out in how many weeks will they have the same number of good behavior stars, equate equation A and equation B
Solve for x
<u><em>Verify</em></u>
For x=6 weeks
<em>Alice</em>
<em>Mack</em>

therefore
In 14 weeks will they have the same number of good behavior stars
