The Cavity-Less Caper

            Daisy Dentifrice is very concerned about her teeth and takes very good care of them. She brushes twice a day and flosses once a day as her dentist has shown her.

            Now that she is on her own and must supply herself with the things she needs to keep her teeth bright, beautiful and forever in her mouth,-she is wondering about the cost of her floss.

            Daisy is now twenty years old, just out-of college and supporting herself. She figures that she uses about 18 inches of dental floss every time she flosses her pearly whites with waxed floss, but when she used unwaxed, she uses about 22 inches. Every 6 months she visits her dentist 'for a check up. She gives Daisy a free package of dental -floss containing 50 yards (waxed cinnamon flavored). Her mother, who is now 45 years old, puts a container of floss of 100 yards (unwaxed) in her stocking at Christmas each year.

In the store she finds many types from which to choose:

Unwaxed, 63 yards @ $1.19

Waxed, mint or cinnamon, 50 yards @ $1.09

Waxed, 100 yards @ $2.49

Waxed mint, 100 yards @ $.99

Unwaxed or waxed, 100 yards @ $ 1.39

Waxed, 200 yards @ $3.79

Natural flossing ribbon, 30 yards @ $3.59

(uses all natural ingredients including bees wax)

HOW MUCH MONEY WILL DAISY DENTIFRICE SPEND ON HER DENTAL FLOSS IN HER LIFE TIME?
