A crime statistics chart shows a 12% decline in burglaries from 250 incidents last year. How many burglaries occurred this year?

Explanation:
When a quantity declines by a percentage, you subtract that percentage of the original amount from the original total. Here, 12% of 250 is 0.12 × 250 = 30. Subtracting 30 from 250 gives 220 burglaries this year. The other numbers would reflect different declines: for example, a drop of 20 corresponds to 8%, a drop of 10 corresponds to 4%, and a drop of 40 corresponds to 16%. Only a 30-decrease matches a 12% decline, so 220 is the correct result.
