I need an objective quantity and all the constraints to determine the point of maximum profit..

Chocolate covered peanuts are $40 for each case

Chocolate covered pretzels are $55 for each case

It takes a machine to 2 hours and a man 5 hours to make a case of peanuts

and a machine 6 hours and a man 4 hours to make a case of pretzels

there are only 150 machine hours and only 155 man hours available..

I want to make the MAXIMUM profit!

any help will be greatly appreciated
