Day 1: .1
Day 2: .2(Double) or .4(Because of .3+.1). Choose .2 for being lower
Day 3: .4 or .5. Choose .4 for being lower.
Day 4: .8(Double) or .7(Because of.4+.3). Choose the lower one .7. Hope it is clear!

Hi,

What was your source for this problem? Can you post the original text because it's pretty clear that the text you've provided is hard to follow.

Thanks,
