Question: James decides to try and collect rare artifacts in the field. He spends 6 months researching before going on a 2-year-long expedition for his first find. The second artifact takes 3 times as long for the research and discovery. How long did it take him to find both?
Answer: Step-by-step reasoning process: The research took 6 / 12 = .5 years. So it took 2 + .5 = 2.5 years for the first artifact. It takes 2.5 * 3 = 7.5 years for the second. So in total it took 2.5 + 7.5 = 10 years to find both.
So the answer is 10.

Question: Sophie buys five cupcakes at $2 each, six doughnuts at $1 each, four slices of apple pie at $2 per slice, and fifteen cookies at $0.60 each. How much does she spend in all?
Answer: Step-by-step reasoning process: Five cupcakes cost 5 x $2 = $10. Six doughnuts cost 6 x $1 = $6. Four slices of apple pie cost 4 x $2 = $8. And, fifteen cookies cost 15 x $0.60 = $9. Therefore, Sophie spends $10 + $6 + $8 + $ 9 = $33.
So the answer is 33.

Question: Albert wants a paintbrush that costs $1.50, a set of paints that costs $4.35, and a wooden easel that costs $12.65. Albert already has $6.50. How much more money does Albert need?
Answer: Step-by-step reasoning process: The total cost of the paintbrush, the paints, and the wooden easel is $1.50 + $4.35 + $12.65 = $18.50. Albert needs $18.50 − $6.50 = $12 more.
So the answer is 12.

Step-by-step reasoning process: There are 60 minutes in an hour so 1 hour 20 minutes = (60 + 20) minutes = 80 minutes. He will spend a total of 80 + 10 = 90 minutes. 90 minutes is = (60 / 60) hours and 30 minutes = 1 hour 30 minutes = 0130 in 24 - hr time. He has to leave 0130 hours earlier than 0900 i.e. 0900 - 0130 = 0730 hours.
So the answer is 730.
