A manufacturing firm produces two precast concrete products: wall panel and roof slabs. These products are processed using two machines A and B. A wall panel requires 2 hours on machine A and 6 hours on machine B. A roof slab requires 5 hours on machine A and 2 hours time on machine B. There are 12 hours per day available on machine A and 8 hours on machine B. The profit gained by the manufacturer from a wall panel is N280 and from a table is N108 Using the extreme point method, solve this Leaner Programming problem to find the dail production of each of the two products.
