The break-even sales amounts is 36 or 224.
Step-by-step explanation:
Consider the provided function.

Where x is the number of televisions sold (in hundreds) and P is the profit.
We need to calculate the break-even sales amounts.
the break-even sales amounts is the sales amounts that result in no profit or loss.
That means substitute P=0 and solve for x.



Substitute a=4, b=-13 and c=4 in above formula.




Therefore, the break-even sales amounts is 36 or 224.
243 + 62-28 = n
243 + 34 = n
277 = n
n= 277
