Final answer:
The percent increase of the temperature from 14 degrees to 28 degrees Fahrenheit is 100%.
Step-by-step explanation:
To find the percent increase in temperature, we need to calculate the difference between the initial and final temperatures and then divide that by the initial temperature. In this case, the initial temperature is 14 degrees Fahrenheit and the final temperature is 28 degrees Fahrenheit.
The difference is 28 - 14 = 14 degrees Fahrenheit. To calculate the percent increase, we divide the difference by the initial temperature and multiply by 100:
Percent Increase = (Difference / Initial Temperature) × 100
Percent Increase = (14 / 14) × 100 = 100%
