In a city of 50,000 residents, 2% are under the age of 10. If a new law requires that 10% of children in the city attend a legal literacy program, how many children need to be enrolled?
Answer
100 children.
The correct answer is 100 children. — Compute 10% of 1,000 children for the program: 0.10×1,000=100.
Step-by-step solution
- Compute 2% of 50,000 to find number of children: 0.02×50,000=1,000.
- Compute 10% of 1,000 children for the program: 0.10×1,000=100.
Common mistake: Multiplying 2% and 10% directly instead of stepwise.
Concept tested: Application of percentages in legal context
