The management at a plastics factory has found that the maximum number of units a worker can produce in a day is 30. The learning curve for the number N of units produced per day after a new employee had workers t days is modeled by N=30( 1-e^kt). After 20 days on the job, a new employee produces 19 units. How many days does the model predict will pass before this employee is producing 25 units per day?
