Step-by-step explanation:
Hope this is right and helps!
We have been given that in 1983, the per capita consumption was 39.7 pounds, and in 1989 it was 47 pounds.
Let us assume t=0 corresponds to year 1980.
Hence, we can express the given information as ordered pairs as (3,39.7) and (9,47).
We can to find a linear function passing through these points. Let us first find slope of the linear function:

We can write the required linear function as:

Upon simplifying this, we get:

In order to find per capita consumption in 1995, we need to substitute t=15 in this function.

Therefore, we would expect the per capita consumption of chicken in 1995 to be 54.3.
