The answer is d. 8,120 foot-pounds
Answer:
846.06 units
Step-by-step explanation:
The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation as follows :
...(1)
We need to find out the maximum amount of profit the company can make.
For maximum profit put dy/dx = 0
So,
![\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdx%7D%28-4x%5E2%20%2B%20183x-%201247%29%3D0%5C%5C%5C%5C-8x%2B183%3D0%5C%5C%5C%5Cx%3D%5Cdfrac%7B183%7D%7B8%7D%5C%5C%5C%5Cx%3D22.87)
Put x = 22.87 in equation (1). So,
![y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06](https://tex.z-dn.net/?f=y%20%3D%20-4%2822.87%29%5E2%20%2B%20183%2822.87%29-%201247%5C%5C%5C%5C%3D846.06)
So, the maximum profit is 846.06 units.
For it’s A= 0.01
And for B it’s B= 9800
86/100, 7/8, 0.9
Work:
0.9 = 0.9
86/100 = 0.86
7/8 = 0.875
7/8 = x/100
8x/8 = 700/8
x = 87.5
