Answer:
See below
Explanation:
With regards to the above information, we can write out the equation to be;
P = (10,900 + y)($6 - 0.0001y)
= 65,400 - 1.09y + 6y - 0.0001y^2
= 65,400 + 4.9y - 0.0001y^2
dp/dx = 4.9 - 0.002y
Set equal to zero to find maximum
4.9 - 0.002y = 0
y = 8,000
So, maximum profit is $
