<span> 0=4+n over 5
In number form the equation is
</span>

<span>We want to isolate n, so to undue division we multiply, we'll multiply each side by 5 Leaving the equation as
</span>

<span>
Next we'll subtract 20 from each side to isolate n
The equation would now be
</span>

<span>
So the answer is
N=-20</span>

Answer:
15
Step-by-step explanation:
To find the minimum amount of items, x, that need to be sold for the manufacturer to make a profit, we can use the quadratic formula
