• The gift certificates are each in multiples of
  5. There is a 100 range in the value of the
  gift certificates, which start at 25. The mean
  value of all seven gift certificates is 80, and
  the median and the mode are both 70.
• The certificate from The Athlete's Alley is worth
  the most, and the one from Gorgeous Candy is
  worth the least.
• The total value of the gift certificates from CD
  Corner, Don's Deli, and the Fancy Footwear Shop
  is 270, but the Fancy Footwear certificate is
  worth 50 more than the one from Don's Deli. The
  CD Corner gift certificate is equivalent to the
  mean for this group of 3.
