We can see a pattern emerge in the payments over the first few weeks. The first week we see the flat rate, $5.00. The next week is $5.50. This could be either and addition of $0.50 every week, or a %10 growth. When we look at the third week, if it were an addition of $0.50, we would expect to see a cost of $6.00, but instead we see $6.05. With this we can conclude that every week the buyer pays %10 more than the last week.
