Judy works at a local bowling alley. She currently makes $300 per week after taxes plus $60 extra cash every other week for cleaning the lanes. Judy is trying to save up for a car. She really wants a Bug. She knows that she can buy a used Bug in good condition for between $6,600 and $9,900. The equation below represents this situation where x is the number of weeks worked and P is the price of the car:

one half times sixty x plus three hundred x equals P.

What is the minimum number of weeks that Judy needs to work to buy her Bug?
