Question

Suppose that the price per unit in dollars of a cell phone production is modeled by p = $45 − 0.0125x, where x is in thousands of phones produced, and the revenue represented by thousands of dollars is R = x · p. Find the production level that will maximize revenue.
_______ thousand phones

Answer 1

see last question you posted. here,
R=x(45-.0125x) then proceed as in the other problem

R=45x-.0125x^2
multiply through by 80
80R=80*45x-x^2
x^2-80*45+80R=0
for max, x=-b/2a=40(45)

Answer 2

Answer 3

véase la última pregunta informados. aquí,
R = x (45 .0125x) a continuación, proceder como en el otro problema

R = 45x-.0125x ^ 2
se multiplican a través de 80
80R = 80 * 45x-x ^ 2
x ^ 2-80 * 45 + 0 = 80R
para max, x = -b / 2a = 40 (45)
