Problema Solution

It costs a business $20 to make one compact disk player and $10 to make one radio. Each week the company must make a combined total of at least 50 cd players and radios. At least as many cd players as radios must be manufactured. Determine how many cd and radios should be made to minimize weekly costs.

Answer provided by our tutors

let

x=amount of compact disks

y= amount of radios


Constraints:

x+y≥50

x≥y

x≥0


Objective function: f(x,y)=20x+10y


we need to find the minimum and that's why we consider the vertices:

(0,0) (50,0) and (25,25)


for (0,0) it can't be the case since there must be some production


for (50,0) we have f(50,0) = 20*50 + 10*0 = 1000


for (25, 25) we have f(25,25) = 20*25 + 25*10 = 750


there should be 25 cds and 25 radios produced to minimize the weekly cost.
