Nina and her mom helped organize the auction fundraiser to help pay for the 8th grade musical. Seven local stores each donated a gift certificate to be redeemed for merchandise. The gift certificates will be auctioned off at the big event. The Athlete's Alley, Bay State Basement, CD Corner, Don's Deli, Elk's Software, Fancy Footwear Shop, and the Gorgeous Candy Boutique have all participated. 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 stores. What is the value of the gift certificate from each store? |
