conversations.value: There's a sale at your favorite "Any item $10" retailer. If you buy 1 shirt you pay $10. If you buy 2, you get the second one at a 50% discount. If you buy 3, you get the third one at a 60% discount. How much money did you save if you bought 3 shirts?
  Give me a solution to this problem

conversations.value: The first shirt has no (0%) discount off the regular price ($10), therefore your discount is = 0% * $10 = $0
  The second shirt has a 50% discount off the regular price ($10), therefore your discount is = 50% * $10 = $5
  The third shirt has a 60% discount of the regular price ($10), therefore your discount is = 60% * $10 = $6
  Therefore in total, you save $0 on the first shirt, $5 on the second one and $6 on the third one = 0+5+6 = $11
