I have been thinking about the turkey dinner I will be making this Thanksgiving and I need your help.  Altogether  I will be having  13 people for dinner. Use the chart below:

     Number of People          Turkey  (pounds)  needed
                7-8                                   12
                9-10                                 14
                11-12                               16
                13-14                               18
                15-16                               21
                17-18                               24

The directions on the wrapper for the turkey states that I need to bake the turkey 20 minutes per pound.
If we want to eat at 2:00 p.m., what time do I need to put the turkey in the oven?
