You can put this solution on YOUR website!
If I read it right, in 4 weeks
100%281.3%29%5E4+=+100%2A2.856
285.6
In 4 weeks 286 cases will be reported
I get this by saying:
At end of 1st week:
cases = 100+%2B+100%2A.3+=+100%2A1.3
At end of 2nd week:
cases = 100%2A1.3+%2B+.3%2A100%2A1.3
cases = 100%2A%281.3%29%2A%281+%2B+.3%29
cases = 100%2A1.3%5E2
And at end of 4th week:
cases = 100%2A1.03%5E4
