If I have a 500.00$ balance and I earn 10 percent of my balance everyday how long would it take me to make 1500.00 a day?

1500 = 500(1 + .10)    where d is the number of days....divide both sides by 500

3 = (1 + .10)d      take the log of both sides

log 3 = log (1 + .10)d       and by a log property we can write

log 3 = d log (1 + .10)     divide both sides by log (1 + .10)

log 3 /log (1 + .10) =  d = about 11.5 days  (or 12 days, rounded)
