To find the zeros, set y = 0

Now try to isolate the (x-4)^2 term (move 10 to right side, divide by -5)

Next take square root of both sides (this cancels the square on (x-4))


For interpretation, x = price, y = profit
We are solving for price where profit = 0.

Given: 
Find: 
Solution: In order to simplify the inequality we can simply add 4 to both sides which would isolate x.
<u>Add 4 to both sides</u>
Therefore, an inequality that would be equivalent to the one that was provided in the problem statement is x < 13.
The answer is 4.5. Hope this helps.
