Answer:
The answer is 18 people who served turkey.
Step-by-step explanation:
In order to determine the amount of persons who eat the turkey, we need to know the final pounds of turkey meat.
The 21 pound turkey consider 15 pound bones, so we have to subtract the bones:
21-5=16
The result is 18 pound turkey meat. Then we need to know how much the people eat each one. They eat 0.8 pounds each one.
Then we divide the remaining turkey with the before value (0.8) to know the amount of persons:
Finally, we round the value to a real value of persons.
There were 20 people who served turkey.
