Question

A baby horse,called a foal, weighed 90 pounds when it was born. After a year, it weighs 540 pounds. Find the percent of change it of it’s weight.

Answer 1

To calculate the percent of change in the foal's weight, subtract the original weight from the final weight, divide the result by the original weight, and then multiply by 100. The foal's weight increased by 500% from birth to one year old.

Step-by-step explanation:

The question is asking to calculate the percent of change in the weight of a foal (baby horse) from birth to one year old. To find the percent of change, we follow these steps:

1. Subtract the initial weight from the final weight to find the change in weight.

Change in weight = Final weight - Initial weight = 540 pounds - 90 pounds = 450 pounds.

1. Divide the change in weight by the initial weight.
2. Multiply the result by 100 to get the percentage.

Percent of change = (Change in weight / Initial weight) × 100 = (450 / 90) × 100 = 5 × 100 = 500%.

The foal's weight increased by 500% from birth to one year old.
