Model A machines each cost $200 to make at a profit of $25 each. Model B cost $3oo to make at a $40 profit. Total number of machines do not exceed 2500 a month. Company has no more $600,000 per month for manufacturing cost. Whats the number of units A and B should produce to maximize the monthly profit?

Answer 1

maximize 25a + 40b
a + b <= 2500
200a + 300b <= 600000

Make 2000 machine B for a profit of 80,000
