Assuming your question is:

Z² - X² - XY     X = -2, Y = 3, Z = -4

Substitute values

(-4)² - (-2)² - {(-2)(3)}

{(-4)(-4)} - {(-2)(-2)} - (-6)

(16) - (4) + 6

16 - 4 + 6

A parent volunteer group is raising money by making custom hats to sell at school activities. They plan to sell the hats for $12
Misha Larkins [42]

Answer:

B. (12-6) n - 50

Step-by-step explanation:

Given that:

Cost of making hat = $6 per hat

Selling price = $12 per hat

Advert cost = $50

Number of hats made = n

The profit or money raised from the sales of hat:

Total Revenue from sales - total cost of production - advert cost

Total Revenue from sales = ($12 * n) = $12n

Total cost of production = ($6 * n) = $6n

Advert cost = $50

Hence,

12n - (6n + 50)

12n - 6n - 50

(12 - 6)n - 50
