question: Colby works for a manufacturing company in the packaging division.  He gets paid $0.20 for every package he completes. If he completes 10 less than 50 packages per hour, how much money, in dollars, does he earn in a typical eight-hour workday?
answer: Ten less than fifty is 50-10=<<50-10=40>>40 packages per hour.
  At $0.20 per completed package. if he completes 40 packages per hour he earns 40*$0.20=$<<40*0.20=8>>8 per hour.
  Thus, in a typical eight-hour day, he earns 8*$8=$<<8*8=64>>64.
