Prealgebra, Tuesday 4/6

We spent most of the class discussing/finishing the exponential problems on yesterday's handout.
We spent the rest of the class working on either the Noon Day Project or the World Imagery Challenge -- which will take up the rest of this week
All this work is in-class so there is NO ASSIGNMENT
But -- there is an EXTRA CREDIT CHALLENGE-- if you saved $100 starting at age 13 and it received compound interest of 5% until age 58 -- how much money would you have?
