How much does he sell a week when he works 5 days a week?Hey there, could you help me solve this math problem: John is a door-to-door salesman.  He visits 50 houses a day.  20% of them buy something from them.  Of those that buy something half buy a $50 set of knives and the other half buy a $150 set of knives.  How much does he sell a week when he works 5 days a week?

conversations.value: There are 50*.2=10 houses buying from him per day
  Of those 10/2=5 buy each type of knife set
  So he gets 5*50=$250 per day from the cheap set
  He also gets 5*150=$750 from the expensive set
  So he makes a total of 250+750=$1000 per day
  That means he makes 1000*5=$5000
