i hope this helped
Simplified Answer: 18z+24
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.
<h2>Solution (a) :-</h2>
Let the cost of the less expensive comic book be x .
Then :-

Using this equation , we can find the cost of the less expensive comic book .
Price of the less expensive book :-





Cost of the less expensive book is 107 .
Therefore , the epice of the less expensive book = $ 107 .
<h2>Solution (b) :-</h2>
Cost of the more expensive book = 11x
Which means :-






Therefore , the price of the more expensive book = $ 1177 .
