Question: Aniyah has 6 times as many birthday candles as Ambika. If Ambika has four birthday candles, how many birthday candles will they have if they put the birthday candles together and shared them equally between themselves?
Answer: If Ambika has four birthday candles, and Aniyah has 6 times as many birthday candles as Ambika, then Aniyah has 4 * 6 = 24 candles. When they put together the candles, the total number becomes 24 + 4 = 28 candles. When they divide the candles and share them equally, each person gets 28 / 2 = 14 birthday candles. The answer is 14.
[Question]A mother planted a 16-inch tree on her son's first birthday. On the day the tree was planted, the boy was 24 inches tall. If the tree grows twice as fast as the boy does, how tall will the tree be by the time the boy is 36 inches tall?
[Answer]The boy grew 36 - 24 = 12 inches since the tree was planted. Since the tree grows twice as fast as the boy, it will have grown 12 * 2 = 24 inches during this time period. Thus, the final height of the tree is 16 + 24 = 40 inches. The answer is 40.
Q: Since 1989, Lily has treated herself to 1 hydrangea plant, each year. Each plant costs $20.00. By 2021, how much money has Lily spent on hydrangeas?
A: She started buying plants in 1989 and it's now 2021 so she has bought these plants for 2021 - 1989 = 32 years. Each plant costs $20.00 and she has bought them for 32 years so she has spent 20 * 32 = $640.00 on hydrangeas. The answer is 640.
Question: TreQuan is throwing rocks in the river and he notices that the bigger the rock, the wider the splash. Pebbles make a splash that is a 1/4 meter wide. Rocks make a splash that is 1/2 a meter wide, and boulders create a splash that is 2 meters wide. If he tosses 6 pebbles, 3 rocks, and 2 boulders, what is the total width of the splashes he makes?
Answer: The pebble's total splash width is 1.5 meters because 6 times 1 / 4 equals 1.5. The rock's total splash width is 1.5 meters because 3 times 1 / 2 equals 1.5. The boulder's total splash width is 4 because 2 times 2 equals four. The total splash width for all the rocks is 7 because 1.5 plus 1.5 plus 4 equals 7. The answer is 7.
[Question]Diane bakes four trays with 25 gingerbreads in each tray and three trays with 20 gingerbreads in each tray. How many gingerbreads does Diane bake?

She uses 3 ounces of beans per day because 2 x 1.5 = 3. She uses 21 ounces of beans per week because 7 x 3 = 21. She buys 2 bags of beans per week because 21 / 10.5 = 2. She spends $16 on the beans per week because 2 x 8 = 16. She spends $2 on the milk per week because 4 x (1 / 2) = 2. She spends $18 per week on her coffee because 16 + 2 = 18. The answer is 18.
