Question

In 2000, there were 356 endangered mammals. Nine years later, 360 species were considered endangered. What was the percent of change? Round to the nearest tenth. 7.RP.3

Answer 1

To calculate the percent of change between two numbers, subtract the old value from the new value, divide the result by the old value, and multiply by 100. In this case, the percent of change is approximately 1.12%.

Step-by-step explanation:

To calculate the percent of change between two numbers, you can use the formula:

Percent Change = ((New Value - Old Value) / Old Value) * 100

Using this formula, we can calculate the percent change between 356 endangered mammals in 2000 and 360 endangered species in 2009:

Percent Change = ((360 - 356) / 356) * 100

Percent Change = (4 / 356) * 100

Percent Change = 1.12%

Therefore, the percent of change is approximately 1.12%.
