Answer:
75 posters
Step-by-step explanation:
Given
---- Revenue
--Cost of production
Required
Determine the number of posters that when cost equals revenue
To do this, we simply equate both equations
i.e. 
Collect like terms.

Multiply through by 3



Divide both sides by 8



X³ + 3x² = 25x + 75
x³ + 3x² - 25x - 75 = 0
x²(x + 3) - 25(x + 3) = 0
(x² - 25) * (x + 3) = 0
(x² - 25) = 0 (x + 3) = 0
x² = 25 x = -3
x = ±5
Hope this helps! :)
Answer:
(3x^2) - 8x
Step-by-step explanation:
A = length x width
