The average PPC is $.11 (There must be a fraction of a cent rounded down that is not shown)
If one click = 11 cents , then 1000 clicks = $110.00 (This is close to your RPM of $114.70. My guess is the fraction of a cent not shown in AVG PPC would make up the small difference of $4.70 per thousand uniques.)
