Optimising+a+Factory

Mrs Bigg wants to set up a new production line to make a brand new product. She already has a buyer lined up - Mr Schopp will buy them from her at 43 pence each. The equipment costs £2450 to buy and £600 to install, and uses a lot of electrical energy to operate - running costs are £50 per day. She has been informed by //Fibb and Scarper//, her management consultants, that the equipment will be capable of producing 15 each minute.
 * Will Mrs Bigg be able to run the production line at a profit?
 * How long will it be before Mrs Bigg has regained her initial capital expenditure?
