A student measured the temperature in degrees Fahrenheit twice during the day:

The morning temperature was 80 degrees Fahrenheit
The afternoon temperature was 92 degrees Fahrenheit
What was the percent increase in temperature?

To calculate the percent increase in temperature, we first need to find the difference between the two temperatures:

92 degrees Fahrenheit - 80 degrees Fahrenheit = 12 degrees Fahrenheit

Next, we find the percentage increase by dividing the difference by the initial temperature (the morning temperature) and multiplying by 100:

(12 degrees / 80 degrees) * 100 = 0.15 * 100 = 15%

Therefore, the percent increase in temperature from the morning to the afternoon was 15%.
