3. A company makes a profit of $50 per software program and $35 per video game. The company can produce at most 200 software programs and at most 300 video games per week. Total production cannot exceed 425 items per week. How many items of each kind should be produced per week in order to maximize the profit? Use linear programming to solve.

mdobbs6856:

Did you graph the inequalities?

iosangel:

i havent even found the constraints

mdobbs6856:

x = the number of software program y = the number of video games \[x \le200\] = inequality A \[y \le300\] = inequality B \[x+y \le435\] = inequality C

mdobbs6856:

or is it 425?

iosangel:

425

mdobbs6856:

Then, 425*

mdobbs6856:

You can put the inequalities in desmos

iosangel:

its not working

mdobbs6856:

It's supposed to look like this

mdobbs6856:

The shaded vertices are (0,0),(0,300),(135,300),(200,235),(200,0)

iosangel:

where did you get 435

mdobbs6856:

The function is equal to \[p=50x+35y\]

mdobbs6856:

I have confused myself. But I found that @shadow had already answered this question before so here, https://questioncove.com/updates/5b8ca82518f14a44aa2c5000

mdobbs6856:

does that help?

24marshpo:

425

surjithayer:

correction delete (425,0) so points are (0,0),(200,0),(200,225),(125,300) now calculate the profit at these points. https://www.desmos.com/calculator/chmavg3edh

surjithayer:

\[x \le200\] \[y \le300\] \[x+y \le 425\]
