Terms

A Factory produces three types of robots called 'John', Kevin' and 'Jane'. Three production steps must be carried out:

• Production of the components takes 5 hours for each robot John and Kevin, and 4 hours for Jane, with a total capacity of 350 hours per week;
  
• Mounting (capacity <= 480) takes 4 hours for John and 5 hours for Kevin;
  
• Testing (capacity <= 300) takes 6 hours for John, 2 for Kevin and 4 for Jane.
  

Profit is $300 for John, $200 for Kevin and $100 for Jane. Of type John robots, 20 have already been ordered. Of type Kevin 15, and of type Jane 10. How many robots of each type must be produced in order to maximize the sales profit?
