@rwby340 The savings for month of June is given in the question. June has 30 days so with $1.10 saving everyday, he would have saved $1.1x30 = $33 in June. But he has $55.0 at the end of June which means that the savings from previous months has been added to June's savings. Similarly, calculated the savings for July which has 31 days and then add that to the savings at the end of June. Hope this helps!
