it’s plumber charges at a flat fee for each job plus an hourly rate for the number of hours the job takes to complete and total cost of the job and dollars can be modeled by the expression 50+65x what does the Constant term and expression represent in the situation

total cost of the job and dollars can be murdered by the expression 50 plus 65x what does the constant term and expression represent in this solution

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
