write a rational function for a local walnut grower that will determine the cost per crate of walnuts in year. will represent the years passed since the year 2000. Assume that the total cost of all walnuts grown was $30,000 in the year 2000 and it has been increasing by 44 dollars per year. Also, assume that the number of crates sold in the year 2000 was 1000 and the number of crates sold has been decreasing by 4 crates per year. Use this information to write a function for c(x), the cost per crate of walnuts.
