Final answer:
To calculate the percent change in temperature from Monday to Tuesday, we use the percent change formula and input the given temperatures. The percent change is a 25% decrease from Monday's high of 80 degrees to Tuesday's high of 60 degrees.
Step-by-step explanation:
The question asks to calculate the percent change in temperature from Monday to Tuesday. The high temperature on Monday was 80 degrees and on Tuesday it decreased to 60 degrees.
To determine the percent change, we use the following formula:
Percent Change = ((New Value - Original Value) / Original Value) x 100%
Plugging in the values from the question:
Percent Change = ((60 - 80) / 80) x 100%
= (-20 / 80) x 100%
= -0.25 x 100%
= -25%
The negative sign indicates that there was a decrease in temperature. Therefore, the percent change in temperature from Monday to Tuesday is a 25% decrease.
