At the shelter for every two dogs, there are about ten cats. If there are a total of 240 cats and dogs at the shelter predict the number of dogs

either 24 or 48  im sure one of those  

Step-by-step explanation:

A - 90 units

B = 0 units

Step-by-step explanation:

Here we have two models A and B with the following particulars

ModelAB    (in minutes)

Assembly2015

Packing          1012

Objective function to maxmize is the total profit

where A and B denote the number of units produced by corresponding models.

Constraints are

These equations would have solutions as positive only

Intersection of these would be at the point

i) (A,B) = (60,40)

Or if one model is made 0 then the points would be

ii) (A,B) = (90,0) oriii) (0, 90)

Let us calculate Z for these three points

ABProfit

60401040

9001080

090720

So we find that optimum solution is

A -90 units and B = 0 units.
