All right, so we want to produce two types of can openers.
00:04
We have manual and the electric.
00:10
Manual and then we have the electric.
00:14
So we know that we use two different types of machines, machines a and b, to produce these two.
00:21
So for the manual can opener, it requires two hours machine a and one hour machine b.
00:31
So for the electric, for the machine a, to produce it, it takes, two hours here and then machine b takes one hour here and then for the electric it takes one hour on a machine a and two hours on b and we know that the maximum number of hours available per month for using machines are 90 and 60 so the total hours are going to be 90 and 60 so we want to know so so we can make a profit on.
01:36
So our profit would be $1 .50 for selling the number of can openers, our manual, plus 2 .5 for the electric.
02:13
So we want to try to sell all of those.
02:16
So we want to try to maximize this.
02:18
So we know our objective function, which is c of x, y.
02:27
It would be a x plus b y so in that case solving this out we're going to have the equation that's 2x plus y even 90 and x plus 2y equal to 60 so let's get rid of the x let's multiply the denominator by negative 2.
03:11
I'm not the denominator the bottom equation by negative 2.
03:20
They have negative 2 x minus 4x, i mean 4 y, it should be negative 120...
