Question

Input/Output Relationship: Assume that the amount of learning you acquire can be summarized by the following relationship (or equation) and that your motivation to learn and the quality of instruction are both rated on a scale from 1 to 10: Amount of learning acquired = 0.2(number of books read) + 0.25(hours spent studying) + 0.15(quality of instruction) + 0.4(motivation to learn). If your motivation to learn rises from 7 to 9, by how much will the amount of learning acquired rise as a result? Show your work.

Answer 1

8%

Explanation:

Motivation to learn represents a 40% of the learning acquired and its rated from 1 to 10. An increase from 7 to 9 represents an increase (of motivation to learn of 20%) But since this quality represent 40% of the total, the real increase in learning is 0.2*0.4=0.08 or 8%.
