Sample problems from Barnyard Math:
#13. Ellen has 3 different flocks of chickens. She has 17 Ameraucana chickens, 32 Rhode Island Red chickens, and 29 Plymouth Rock chickens. On Tuesday, Ellen collected 13 eggs from the Ameraucana, 26 from the Rhode Island Reds, and 18 from the Plymouth Rocks. How many chickens did not lay eggs on Tuesday? Note: chickens lay at most 1 egg a day.
#60. Daisy and Donald are Pekin ducks. Donald works very hard each day to eat exactly twice as many flies as Daisy. Daisy caught 15 flies on Monday. If Donald caught 4 more flies on Tuesday than he did on Monday, how many flies did Daisy catch on Tuesday?
#80. Darrell loves raising goats. He recently bought 3 goat kids for $3 per pound. Their weights were 12 pounds, 13 pounds, and 15 pounds. Darrell gave them good pasture and also fed them a total of 8 bags of concentrated goat feed before he sold them 3 months later. At the sale barn, the goats' weights were 78 pounds, 84 pounds, and 82 pounds. They were each sold for $2 per pound. If each bag of goat feed costs $10, and the sale barn charged a seller's commission of $5 for each goat, what was Darrell's profit from raising the 3 goat kids?
