Question: I would love to understand how to solve this problem: Given a 7-day week, how much does Alex charge for 2 weeks of tutoring if she charges $12 per day?
Can you explain?
Answer: 
A week has 7 days, therefore 2 weeks have 2*7= 14 days
If Alex charges $12 per day, then in $14 days she would charge $12*14 = $168
