To find the number of robberies in Springfield in 2011 after a decrease of 50% from the 2010 figures, we can follow these steps:
1. Start with the number of robberies in 2010, which was 164.
2. Calculate 50% of 164:
\[
50\% \text{ of } 164 = 0.5 \times 164 = 82
\]
3. Subtract this decrease from the 2010 number:
\[
\text{Robberies in 2011} = 164 - 82 = 82
\]
Thus, the number of robberies in Springfield in 2011 was **82**.
