A neighborhood watch program increases membership by 25% from 80 members. How many members after the increase?

Explanation:
A 25% increase means you add a quarter of the original amount to itself. Start with 80 members and find 25% of 80: 0.25 × 80 = 20. Add that to the original 80 to get 100. So there are 100 members after the increase. The other options don’t fit the 25% increase: 70 would be a decrease from 80, 90 is only a 12.5% rise, and 110 is a larger rise (37.5%).
