In a newspaper, it was reported that the number of yearly robberies in Springfield in 2011 was 216, and then went up by 50% in 2012. How many robberies were there in Springfield in 2012?

Answer 1

To calculate the number of robberies in Springfield in 2012, we first need to determine what a 50% increase from the figure in 2011 would be.

1. Start with the number of robberies in 2011: \[ 216 \]

2. Calculate 50% of that number: \[ 50% \text{ of } 216 = \frac{50}{100} \times 216 = 0.5 \times 216 = 108 \]

3. Now, add that increase to the original number of robberies from 2011 to find the total for 2012: \[ 216 + 108 = 324 \]

Thus, the number of robberies in Springfield in 2012 was \( \boxed{324} \).
