A manufacturer of lightweight tents makes two models
Model A 0.9 hour and 0.8 hour
Model B 1.8 hours and 1.2 hours
On a monthly basis, the manufacturer has no more than 864 hours of labor available in the cutting department and at most 672 hours in the assembly division.The profits come to
$25 per tent for model A and $40 per tent for model B. How many of each should be manufactured monthly to maximize the profit?

Can someone please show me how to get this WITH THE WORK!!! Thanks!
