1. Madison's monthly salary is $2,810. If Madison's budget for rent is 26%
of salary, thep how much is budgeted for rent?

Step-by-step explanation:

Madison's rent  = 26% of 2810

                         = 0.26 * 2810

                         = $ 730.60

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
