A computer company develops a new scan disk. The cost $P of producing a scan disk is partly constant and partly varies inversely as the total number of scan disks N produced.
When 2500 scan disks are produced, the total cost is $225000. When 5000 scan disks are produced, the total cost is $425000.
(a) Express P in terms of N.
(b) If the selling price of a scan dish is $120, find the profit percentage if the company produces and sells 1000 scan disks.
(c) If the selling price of a scan disk is $100, what is the minimum number of disks that need to be produced in order to make a profit?
