The membership increases linearly, starting at 160 and increasing by 3 each month. The total dues collected is the sum of dues from each month. Calculate the number of members each month, multiply by $15, and sum for 12 months: $15 \times (160 + 163 + 166 + \ldots + 193) = 15 \times 2124 = \$ 31,770$.
