Final answer:
The combined percentage of turkey eaten exceeds 100%, indicating an error in the question as it is impossible to eat more than the whole turkey.
Step-by-step explanation:
The question asks about calculating the remaining percentage of a turkey eaten by various family members.
Uncle Dave ate 40%, Aunt Kate 25%, cousin Javier 30%, and little Dominic 12%. To find the remaining percentage of the turkey, we add up the percentages consumed: 40% + 25% + 30% + 12% = 107%.
Since the total exceeds 100%, this indicates an error as it's impossible to eat more than the whole turkey. The problem likely contains a mistake because the total amount eaten should not exceed 100%.
