Question

Charlie had 3 hamsters. One of his hamsters had pups. Now he has 12 hamsters. What is the percent increase in the number of hamsters?

Answer 1

The percent increase in the number of hamsters Charlie has is calculated by finding the difference in numbers, dividing by the original amount, and then multiplying by 100, resulting in a 300% increase.

Step-by-step explanation:

To calculate the percent increase in the number of hamsters Charlie has, we first find the difference in the number of hamsters before and after the pups were born. We subtract the original number of hamsters (3) from the new number (12) to get the increase in the number of hamsters, which is 9. Then we divide this increase (9) by the original number of hamsters (3) and multiply by 100 to get the percent increase.

The calculation is as follows: (9 / 3) × 100 = 300%. So, the percent increase in the number of hamsters is 300%.
