Answer 1

To find the population of Babba, you need to calculate using the given information. Based on the given details, the population of Babba is 12,500.

Step-by-step explanation:

To find the population of Babba, we can use the given information:

• 20 percent of the people have one foot, which means 20 percent of the population has one foot.
• The remaining people can either wear no boots or wear two boots.
• The total number of boots worn in Babba is 20,000.

Let's calculate:

1. 20 percent of the population has one foot. So, the rest of the population is 80 percent.
2. Half of the remaining people wear no boots. So, 80 percent of the population wear no boots.
3. Half of the remaining people wear two boots. So, 80 percent of the population wear two boots.
4. Since there are 20,000 boots worn, we can set up the following equation: (80% of the population * 0 boots) + (80% of the population * 2 boots) = 20,000 boots.
5. Simplifying the equation, we get: (0.8 * P * 0) + (0.8 * P * 2) = 20,000, where P represents the population of Babba.
6. Multiplying, we get: 1.6 * P = 20,000.
7. Dividing both sides by 1.6, we find: P = 12,500.
