An entrepreneur has started a new business selling handmade stationery. In order to attract new customers, the entrepreneur has rented a small stand at an upcoming business event and is intending to sell Calendars and Notebooks at a low promotional price.

\n

The printing of each calendar will cost the entrepreneur £2.00 and the printing of each notebook will cost £3.00. The entrepreneur has £600 to spend on printing costs. 

\n

Each calendar will take the entrepreneur 2 hour to make and each notebook takes 1 hour to make. The entrepreneur has 280 hours to make all the items for the stand before the event.

\n

Another business attending the event has agreed to put 30 calendars on their stand, so the entrepreneur must make a minimum of 30 calendars.
