Explanation:

Problem 1

Step1: Identify 2002 baby count

From bar graph, 2002 count = 580

Step2: Calculate percentage

$\text{Percentage} = \frac{580}{2500} \times 100\%$
$\text{Percentage} = 0.232 \times 100\% = 23.2\%$

Step3: Match closest option

23.2% is closest to 25%

Step1: Identify gym and total students

Gym students = 14, Total students = 60

Step2: Calculate percentage

$\text{Percentage} = \frac{14}{60} \times 100\%$
$\text{Percentage} \approx 0.2333 \times 100\% = 23.3\%$

Step3: Match correct option

23.3% matches option D

Answer:

C. 25%
