Lizzy: 20% of the job candidates at a temp agency have experience with Excel. 70% of the candidates are only willing to work day shifts. If a manager picks a candidate at random, what are the odds they know Excel and are willing to work nights?.
Me: Hmmm, let me think. I think this is the detailed solution:

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.

First find the percentage of candidates who are willing to work nights: 100% - 70% = 30%. Then multiply that percentage by the percentage who know Excel to find the percentage who meet both qualifications: 30% * 20% = 6%. Final answer: 6.
