Math Monday: Dental Care (Again)

Back in February 2009, I began putting this unit together, but never got past the first day.  I am going to finally finish the unit this week.  I will not be including elementary math in today's post, but will instead include the link to the 2009 post and just post a couple of word problems for the older students.


Word Problems

- You saved all the money that the Tooth Fairy brought you since you lost your first tooth.  Your last tooth just fell out.  The Tooth Fairy will bring you $1.50 tonight, just as she has done each time you lost a previous tooth.  Most people lose a total of 20 baby teeth.  How much money will you have after the Tooth Fairy visits tonight?  Now imagine you took that money and put it in a savings account.  If the account you choose pays you 3% interest, how much money will you have at the end of the year?

- Uh oh!  You just visited the dentist for a cleaning and they found 2 cavities.  It will take about 45 minutes to have each cavity filled and they will need to be done on different days.  If it takes 15 minutes to drive each way to the dentist, how much time will you need to spend in order to get both cavities filled.
