conversations.value: I need help with this problem:
  A salesman bought a case of 48 sneakers for $576. He sold 17 of them for $20 at a flash sale on Monday, and the rest were sold to a department store for $25 each throughout the rest of the week. How much money, in dollars, was the salesman's profit?

conversations.value: The salesman made 17 × $20 = $340 at the flash sale on Monday.
  There were 48 - 17 = 31 sneakers left.
  At the department store he made 31 × $25 = $775 throughout the week.
  In total he made $340 + $775 = $1115.
  The profit made by the salesman was $1115 - $576 = $539.
