Linear Algebra

A 20-pound turkey that has been thawed at room temperature of 72 degrees is places in the oven at 1:00 pm. The temperature of the turkey is observed in 20 minute intervals to be 79 degrees, 88 degrees, and 96 degrees. A turkey is cooked when its temperature reaches 165 degrees. How much longer do you need to wait until the turkey is done?
