Taking,
x = number of people,
y = pounds of turkey.
This condition can be represented as,
As given in the question, when x = 6 y = 3
Now, putting the values of k in the equation, the equation becomes
Now, we can get the values of y or number of pounds of turkey needed by putting the given x or number of people.
All the calculations are shown in the attached table.
