conversations.value: Martha receives a daily allowance of $12. She decides to save half of this amount every day. In the first week she kept her commitment with the exception of one day when she saved only a quarter of this amount. How much has she saved at the end of this week?
  Give me a clear explanation.

conversations.value: Half of $12 is (1/2)*$12 = $6
  There are 7 days in a week so if she saved half every day except one then she saved half for 7-1 = 6 days
  She saved $6 for 6 days for a total of $36
  A quarter of $12 is (1/4)*$12 = $3
  She saved a quarter once for a total savings of $3+$36 = $39
