Marie has 98 unread messages on her phone. She decides to clear them by reading 20 messages a day. However, she also gets 6 new messages a day. How many days will it take her to read all her unread messages?
Marie will read 20 but gain 6 unread messages a day, so she will lower the number of messages by 20 - 6 = <<20-6=14>>14.
Thus, it will take her 98 / 14 = <<98/14=7>>7 days to read all her unread messages.
