Question: To raise funds for her local soup kitchen, Didi enlisted the help of her family, friends, and neighbors. They donated 10 same-size cakes that she sliced into 8 slices per cake and started selling a slice for $1. A local business owner was so impressed by Didi's efforts that she offered to donate 50 cents for each slice Didi sold. A second business owner also offered to donate a quarter for each slice sold. If Didi sold all the slices, how much money did she raise?
Answer: Step-by-step reasoning process: All the cakes yielded 10 * 8 = 80 slices. Since Didi was selling each slice for $1, it means she sold everything for 80 * 1 = 80 dollars. The first business owner donated 50 / 100 * 80 = 40 dollars. The second business owner donated 25 / 100 * 80 = 20 dollars. Adding both amounts gives 80 + 40 + 20 = 140 dollars.
So the answer is 140.

Question: Hannah ran 9 kilometers on Monday. She ran 4816 meters on Wednesday and 2095 meters on Friday. How many meters farther did she run on Monday than Wednesday and Friday combined?
Answer: Step-by-step reasoning process: Wednesday + Friday = 4816 + 2095 = 6911 meters. 9 km = 9000 meters. 9000 - 6911 = 2089 meters. Hannah ran 2089 meters farther on Monday than Wednesday and Friday.
So the answer is 2089.

Question: Three fifths of the light bulbs in the kitchen are broken. A third of the light bulbs in the foyer are also broken. If 10 light bulbs in the foyer are broken and there are 35 light bulbs in the kitchen, then how many light bulbs are not broken in both the foyer and kitchen?
Answer: Step-by-step reasoning process: There are 35 / 5 = 7 light bulbs to every fifth. 7 * 3 = 21 lightbulbs in the kitchen are broken. There are 35 - 21 = 14 light bulbs in the kitchen that are not broken. There are 10 * 3 = 30 light bulbs in the foyer in total. There are 30 - 10 = 20 light bulbs in the foyer that are not broken. There are 14 + 20 = 34 light bulbs that are not broken in both the foyer and kitchen.
So the answer is 34.
