Answer the following question.
Osborn is testing a new way to get dressed in the morning on school days so he goes faster and can get up later. He tracks his time for the week and on Monday is takes him 2 minutes. On Tuesday it takes him 4 minutes. On Wednesday it takes him 3 minutes. On Thursday it takes him 4 minutes. Before Friday arrives he looks at his old way of getting dressed and sees that it was taking him 3 minutes on average to get dressed. How fast does he have to get dressed on Friday so his weekly average ties his old method?
Step-by-step reasoning process: If it takes on average 3 minutes to get dressed, then it takes 15 minutes total on the school week because 5 x 3 = 15. Thus far this week it has taken him 13 minutes to get dressed because 2 + 4 + 3 + 4 = 13. To tie his previous method, he needs to take 2 minutes on Friday because 15 - 13 = 2.
The answer is 2.

Answer the following question.
Gerald wants to buy a meat pie that costs 2 pfennigs. Gerald has 54 farthings, and there are 6 farthings to a pfennig. How many pfennigs will Gerald have left after buying the pie?
Step-by-step reasoning process: First convert the number of farthings Gerald has to pfennigs by dividing by the exchange rate: 54 farthings / 6 farthings / pfennig = 9 pfennigs. Then subtract the cost of the meat pie to find how many pfennigs Gerald has left: 9 pfennigs - 2 pfennigs = 7 pfennigs.
The answer is 7.

Answer the following question.
Carter has a 14-hour road trip. He wants to stop every 2 hours to stretch his legs. He also wants to make 2 additional stops for food and 3 additional stops for gas. If each pit stop takes 20 minutes, how many hours will his road trip become?
Step-by-step reasoning process: He has a 14 - hour trip and wants to stop every 2 hours so that's 14 / 2 = 7 pit stops. He will make 7 pit stops plus 2 more for food and 3 more for gas for a total of 7 + 2 + 3 = 12 pit stops. Each pit stop will take 20 minutes and he is making 12 stops so that's 20 * 12 = 240 minutes. 60 minutes are in an hour and he's adding 240 minutes to his trip so that's 240 / 60 = 4 more hours. His trip started as 14 hours and he will add an additional 4 hours in pit stops for a total of a 14 + 4 = 18 hour long trip.
The answer is 18.

Answer the following question.
John and his two brothers decide to split the cost of an apartment. It is 40% more expensive than John's old apartment which costs $1200 per month. How much does John save per year by splitting the apartment compared to living alone?
Step-by-step reasoning process: His old apartment cost 1200 * 12 = $14,400 per year. His new apartment 1200 * 1.4 = $1680 per month. That means it cost 1680 / 3 = $560 per month. So it cost 560 * 12 = $6720. So he saves 14400 - 6720 = $7680.
The answer is 7680.
