NanoSoft Inc. produces hard drives and memory ram parts for computers. To produce these parts, they require two limited resources which are: machine time and microchips. The machine operates for 20 days a month, 10 hours a day. Hard drives take 8 minutes to produce while memory ram takes 2 minutes. Each hard drive uses a total of 20 microchips and memory ram uses 4 microchips. They have a total of 40000 microchips each month. Since computers will typically need 2 or more memory ram, but only one hard drive, the company would like to produce at least twice as many memory ram than hard drives. The unit profit margin for hard drive is $50 while the unit profit margin for memory ram is $12. How many memory cards should the company produce to operate optimally?
