B. 33.33%
C. 10.53%
D. 49.47%

Answer 1

To calculate the percent change in temperature from 38 degrees to 57 degrees, you subtract the original temperature from the new temperature and then divide by the original temperature. The percent change is 50%, making option A the correct answer.

Step-by-step explanation:

The question asks for the percent change in temperature from 38 degrees to 57 degrees. To calculate the percent change, we use the formula:

Percent Change = (Change in Value / Original Value) × 100%

First, find the change in temperature:

• Change in Temperature = New Temperature - Original Temperature
• Change in Temperature = 57 degrees - 38 degrees
• Change in Temperature = 19 degrees

Next, apply the percent change formula:

• Percent Change = (19 degrees / 38 degrees) × 100%
• Percent Change = 0.5 × 100%
• Percent Change = 50%

The correct answer is A. 50%.
