Help with projected averages

Apr 2008
Can some1 help with the following problem and I hope I put the thread in the right forum!!!

This is what I am trying to work out:
Take a month with 30 days. The first day I lose 5% of my betting bank. There are now 29 days left and my target is to average 1% per day.

Taken into account that i lost 5% on day one , is there a formula that I can use to calculate what I need to average over the remaining 29 days to hit a 1% average?

Many thanks for any time and help
