The telephone company made this table to show the number of telephones in the homes they surveyed:
Phones in home 0 1 2. 3 4 or more
Number of homes 733 5642 12
If these homes are representative of the community of 100,000 homes that the
company serves, about how many homes would you predict have 4 or more
telephones?

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
