You can put this solution on YOUR website!
Let +n+ = total number of dogs eaten by day +n+
+n+-+1+ = total number of dogs eaten by day +n-1+
+4%2A%28+%28+1+%2B1.1%29%5En+-+%28+1+%2B1.1%29%5E%28+n-1+%29%29+
+4%2A%28+2.1%5En+-+2.1%5E%28+n-1+%29+%29+
-------------------------------
check:
how many dogs eaten on day 3 ?
+4%2A%28+2.1%5E3+-+2.1%5E2+%29+
+4%2A%28+9.261+-+4.41+%29+
+4%2A4.851+=+19.404+
OK

Definitely get a 2nd opinion on this
( unless you know the answer )
