So where's the problem? Every hour you use (100 x 2 + 5 x 58) mA.minutes. Divide by 60 gives you mAh. 5000 divided by that number gives you how many hours the battery should last.
In the real world it won't last quite that long but it should be close. If your input numbers are accurate, for example initially you said 130mA not 100mA and that makes quite a difference.
