Suppose Mr. Wong manages a blueberry farm in Yuen Long. From 2001 through 2022, the amount (in kg.) of blueberry harvested can be modeled by W(x)=20x2+30x+5 The average cost per kg. (in HK dollars) can be modeled by C(x)=3x2−5x+12 where x is the number of years since 2001. Write polynomial T(x) that can be used to model Mr. Wong's total costs.
