An oil company transforms crude oil in 2 types of byproducts: A and B.

It costs $65,000 to buy 1000 barrels of crude oil, 500 of it will be transformed in A and 500 in type B.

Both A and B can be sold directly to the consumer or go through a process:

If they are sold directly, A is sold by $80,000 per 1000 barrels and B is sold by $65,000 per 1000 barrels.

If they are sold after going through the process: it takes 1 hour for 1000 barrels of A to go though the process and they can be sold for $145,000 per 1000. It takes 45 minutes for 1000 barrels of B to go through the process and they can be sold for $125,000 per thousand barrel.

Everyday, a maximum of 20,000 barrels can be sold, and the machine that does the process described above will work for a maximum of 8 hours.

a) What is the maximum daily profit?
