"Jose wants to put wall-to-wall carpeting in a rectangular room that measures 11 feet by 12 feet. The carpet costs $4.12 per square foot. How much will it cost for Jose to buy the carpet for the room? Write your answer in the box. you may use the sketch area to draw a diagram or show where, if you would like!" links will be reported​

$543.84

Step-by-step explanation:

Find the area of the room:

11*12 = 132ft^2

Multiply the area by the cost per square foot:

132*4.12 = 543.84 dollars

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
