Direct and inverse variation problem may be solved (1) using a proportion, or (2) by finding the "k" of variation. Students in this course often use the first method, even when the teacher's instructions say to use the "k" of variation to solve. Please take some time to be sure you can use both methods because you will be asked specifically to use both. Then use this discussion as an opportunity to compare and contrast the two methods.

The two method solving direct or inverse variation differ from each other by the introduction of the K constant in variation.

Explanation:

The former (proportion) makes use of ratio principle while the latter uses a formula connecting the variable factors

rational decision making is a multi-step process for making choices between alternatives. the process of rational decision making favors logic, objectivity, and analysis over subjectivity and insight. the word “rational” in this context does not mean sane or clear-headed as it does in the colloquial sense.
