Solve for the indicated variable: 2p + 5r = q for p

Step-by-step explanation:

We need to solve the equation for p

Our aim is to get p alone

Subtract 5r on both sides

Now divide both sides by 2 to get 'p' alone

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
