Question: Can you give me some step-by-step instructions for this math problem: John plans to save money from working.  He gets paid $2 per hour and works 5 hours a day for 4 days a week.  If he wants to save $80 how many weeks will it take him?
Answer: 
He gets paid 2*5=$10 a day.
So he gets paid 10*4=$40 a week.
That means it would take 80/40=2 weeks to save up the money.
