My question is: Jill runs a business breeding llamas. Nine of her llamas got pregnant with 1 calf, and 5 of them got pregnant with twins. After they give birth, Jill traded 8 of the calves for 2 new adult llamas. Then she sells 1/3 of her herd at the market. How many total llamas (calves and adults) does Jill have now? Your thoughts:
The number of calves that will be born as twins is 5 * 2 = 10 calves. The total number of adults and calves before the trade is 9 + 5 + 9 + 10 = 33. Jill had 33 - 8 = 25 left for trading 8 of the claves. But, she got 2 adult llamas in return, so she now has a total of 25 + 2 = 27 llamas. She then sold 27 / 3 = 9 llamas in the market. So, Jill has 27 - 9 = 18 llamas now. The final answer: 18.
