conversations.value: The average score on last week's Spanish test was 90.  Marco scored 10% less than the average test score and Margaret received 5 more points than Marco.  What score did Margaret receive on her test?
  Give me a clear explanation.

conversations.value: The average test score was 90 and Marco scored 10% less so 90*.10 = 9 points lower
  The average test score was 90 and Marco scored 9 points less so his test score was 90-9 = 81
  Margret received 5 more points than Marco whose test score was 81 so she made 5+81 = 86 on her test
