Final answer:
Percent Change = [(New Value - Old Value) / Old Value] x 100. Therefore, the change in Max's course load from 6 to 5 classes can be expressed as a decrease of 16.67%.
Step-by-step explanation:
To express the change from 6 classes to 5 classes as a percent, we can use the formula:
Percent Change = [(New Value - Old Value) / Old Value] x 100
Plugging in the values, we get:
Percent Change = [(5 - 6) / 6] x 100
= -16.67%
Therefore, the change in Max's course load from 6 to 5 classes can be expressed as a decrease of 16.67%.
