1990 Tax Revenue: $250,000
1991 Tax Revenue: $250,000 * 1.035 = $257,500
1992 Tax Revenue: $257,500 * 1.035 = $265,563
1993 Tax Revenue: $265,563 * 1.035 = $273,939
1994 Tax Revenue: $273,939 * 1.035 = $282,641
1995 Tax Revenue: $282,641 * 1.035 = $291,676
1996 Tax Revenue: $291,676 * 1.035 = $301,053
1997 Tax Revenue: $301,053 * 1.035 = $310,765
1998 Tax Revenue: $310,765 * 1.035 = $320,808
So in 1998, the small city would receive $320,808 in tax revenue.
