Answer
If the assessed home value is greater than ${{\$}} 32,000$, then the first bill would be a better deal.
Work Step by Step
Let $ x $ be the assessed home value.
Better deal = smaller cost to the homeowner.
We want x for which
(Cost of Bill 1) $ \lt $ (Cost of Bill 2)
$1800+0.03x \lt 200+0.08x\qquad $ ... add $-0.03x-200$
$1600 \lt 0.05x\qquad $ ... multiply with $20$
$32,000 \lt x $
If the assessed home value is greater than ${{\$}} 32,000$, then the first bill would be a better deal.
