(ii) The profit function, in dollars, for a product is given by Π(x) = −x3 + 76x2 − 380x − 2800, where x is the number of units produced and sold. If break-even occurs when 10 units are produced and sold, (a) Find a quadratic factor of Π(x).(b) Find a number of units other than 10 that gives break-even for the product.

(a) The factors are (x + 4), (10 - x) and (x - 70).

(b) There is a break-even for 70 units of the product.

Step-by-step explanation:

(a)

Factorizing the term in parentheses,

Then

The factors are (x + 4), (10 - x) and (x - 70).

(b)

Break-even occurs when Π(x) = 0

or or

Since x cannot be negative, x = 70.

Hence, there is a break-even for 70 units of the product.

im like 90% sure its a meme

step-by-step explanation:

good luck tho

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000
