Letter to editor: Rates increase

I must be dumber than I thought.

With last year’s rates being  $1869.71, and a 10 per cent Special Rate Variation (SRV) in place for this year, I thought they'd rise by $186.97, but no, apparently a 10 per cent increase is actually $212.07 or if I've got it right 11.35 per cent .

Can someone please check my maths?
