The profit (SP) of selling a mobile phone is partly constant and partly varies directly as the number of phones (n) sold. When 20 phones were sold, the profit will be $3,000. When 25 phones were sold, the profit will be $5,400. (a) Express P in terms of n. (b) Find the profit when 40 phones were sold. (c) Find number of phones were sold if the targets profit is $23,640?
