d)
Using your answer from part b and your equation from part c, what is the most money you can hope to earn from your business?
Part b is x <= 714
Part c is T=50x
To find the most money you can hope to earn from your business, substitute the maximum value of x (which is 714) into the equation from Part c:
T = 50x
T = 50 * 714
T = 35,700
So, the most money you can hope to earn from your business is $35,700.
