Solving Optimization Problems

1.Understand the problem. Clearly identify what quantity is to be maximized or minimized.(in this case,we are looking for the price that will maximize the profit)

2.Create equations relevant to the context of the problem, using the information given. (One of these should describe the quantity to be optimized. We'll call this the fundamental equation. i.e P(x)=R(x)-C(x)=> P(x)=xS.P(x)-C.P(x),,,,,,,,,,
s.p(selling price),c.p(cost price),P(profit).
critical point is at P'(x)=0)

2.If the fundamental equation defines the quantity to be optimized as a function of more than one variable, reduce it to a single variable function using substitutions derived from the other equations.
3.Identify the domain of this function, keeping in mind the context of the problem. which is (0<x<8*10^5)=>[0, 8*10^5]
4.Find the extreme values of this function on the determined domain.
5.then finally Identify the values of all relevant quantities of the problem.


my little contribution in helping you solving the problem

Martinez39s:
I have gotten that it's 10 – (x/10⁵). For one last time, check your question again.

Martinez39s:
I don't understand your question. Restate it again. It seems like an optimisation problem in differential calculus.

Also clarify if you meant 10 – (x/10⁵) instead of (10 – x)/10⁵. I will solve the problem for you.

bro I take God beg you
help me with this

A utility company has a small power plant that can produce a kilowatt hours of electricity daily at a cost of 10 - x/10^5 cents each for 0 < x < 8 x 10^5. Consumers will use 10^5(10 - p/2) kilowatt hours of electricity daily at a price of p cents per kilowatt hour. What price should the utility charge to maximize its profit?

Martinez39s:
Δy = 3(x + Δx)² – 7(x + Δx) – 4 – 3x² + 7x + 4
= 6x(Δx) + 3(Δx)² – 7Δx

Δy/Δx = 6x + 3(Δx) – 7

The limit of 6x + 3Δx – 7 as Δx approaches 0 is 6x – 7. Hence dy/dx = 6x – 7.

Δy = 7(x + Δx) – 7x
= 7(Δx)

Δy/Δx = 7.

The limit of 7 as Δx approaches 0 is 7. Hence dy/dx = 7.

Your work is cool..
You should make use of external CSS. That way your HTML page can be read and understood easily (Just in case you make mistakes)
