Write a real world problem that could be solved by using the equation 3x-25= 125. then solve the equation

There can be many example for this equation like:

1. There are three friends and all have the same amount of money. Together they give $25 in a restaurant and they are left with $125. How much money did each have?

We can solve this like:

Let each friend had 'x' money so three friends had 3x money.

They gave out $25, means 3x-25 and are left with $125.

So, complete equation becomes :

Solving for x we get;

x = 50

So, each friend had $50.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
