Q: Eliza has 4 siblings. The total height of all 5 siblings combined is 330 inches. Two of her siblings are both 66 inches tall. Another sibling is 60 inches tall. If Eliza is 2 inches shorter than the last sibling, how tall is Eliza?
A: The first three siblings are 66 + 66 + 60 = 192 inches tall. Since the total of all the siblings is 330 inches, Eliza and the last sibling are 330 - 192 = 138 inches tall combined. If Eliza's height = h, 138 inches = h + (h + 2). (138 - 2) / 2 = 68 inches. Eliza is 68 inches tall. The answer is 68.
Question: Lorraine made a pan of brownies and cut them into 16 pieces. Her children ate 25% of the brownies when they got home from school. After dinner, the entire family ate 50% of the remaining brownies. After everyone went to bed, Lorraine ate 1 more brownie. How many brownies are left over?
Answer: Her children ate 25% of the 16 brownies so they ate .25 * 16 = 4 slices. There were 16 brownies and the children ate 4 slices, leaving 16 - 4 = 12 brownies. The family ate 50% of the remaining 12 brownies so they ate .50 * 12 = 6 brownies. There were 12 brownies and they ate 6 which leaves 12 - 6 = 6 brownies. Lorraine had 1 more of the 6 remaining brownies which leaves 6 - 1 = 5 brownies. The answer is 5.
[Question]Carlson bought land that cost $8000 and additional land that cost $4000. He initially owned 300 square meters of land. If the land he bought costs $20 per square meter, how big is his land after buying the new land?
[Answer]Carlson bought land that cost $20 per square meter, therefore the size of the land he bought is 8000 / 20 = 400. And the size of the other land he bought is 4000 / 20 = 200. Therefore the total size of the land he owns is 400 + 200 + 300 = 900. The answer is 900.

Question: Sandy's goal is to drink 3 liters of water in a day. She drinks 500 milliliters of water every after 2 hours. After how many hours will she be able to drink a total of 3 liters of water?
Answer: Since there are 1000 milliliters in 1 liter, then 3 liters is equal to 3 x 1000 = 3000 milliliters. She needs to drink 3000 / 500 = 6 sets of 500 milliliters of water. So, she will be able to drink a total of 3 liters after 6 sets x every 2 hours = 12 hours. The answer is 12.
Q: James hurt himself exercising. The pain subsided after 3 days, but he knew that the injury would take at least 5 times that long to fully heal. After that, he wanted to wait another 3 days before he started working out again. If he wants to wait 3 weeks after that to start lifting heavy again, how long until he can lift heavy again?
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The injury would be fully healed after 3 * 5 = 15 days. So he would start exercising again in 15 + 3 = 18 days. He would then wait for 3 * 7 = 21 more days to start lifting heavy again. That means he needs to wait 18 + 21 = 39 days. The answer is 39.
