Answer:
Slope = 
Step-by-step explanation:
(-9, -8) & (-15 , -16)
Slope = 
![= \frac{-16-[-8]}{-15-[-9]}\\\\= \frac{-16+8}{-15+9}\\\\= \frac{-8}{-6}\\\\= \frac{4}{3}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-16-%5B-8%5D%7D%7B-15-%5B-9%5D%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-16%2B8%7D%7B-15%2B9%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-8%7D%7B-6%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B4%7D%7B3%7D)
The Profit = Revenue - CostP ( x ) = ( 40 x - 0.5 x² ) - ( 5 x + 15 ) = = 40 x - 0.5 x² - 5 x - 15 = - 0.5 x² + 35 x - 15The maximum profit is when: P`( x ) = 0P ` ( x ) = ( - 0.5 x² + 35 x - 15 ) ` = - x + 35- x + 35 = 0x = 35 ( the number of units )P max = - 0.5 · 35² + 35 · 35 - 15 = - 612.5 + 1225 - 15 = 597.5Answer: The maximum profit is 597.5 and the number of units is 35.
