the supervisor i'll give you a penny taday and double your pay every day for 30 days if you work for me.
use a table to slove this problem
what balance after 30 days?
what is the interest rate and number of periods for this?
what is a equstion for this also?

1 + 2 + 4 + 8 + ... for 30 terms
a GS , where a = 1 , r = 2 ,n = 30
sum(30) = a(r^n  1)/(r1)
= 1(2^30  1)/1 = 1,073,741,823 pennies
