A dairy spends $26,000 per year to maintain its barns and equipment. It costs $3000 per year to feed and care for each dairy COW. (a) Using C for the number of dairy cows and E for the total yearly expense, in dollars, find a formula that gives the total yearly expense as a linear function of the number of dairy cows. E = (b) Use functional notation to express the total expense if the dairy has 20 cows. OE(20) E(20C) 20E E(26,000) E(3000) (c) Calculate the value from part (b). $ tA
