Question 297243
Happiness is directly related to optimism and inversely related to anger. If happiness is 8 when optimism is 6, anger is 2. What is happiness when optimism is 4 and anger is 4?

H happiness, O optimism, A anger, k an arbitrary constant
H = k * O, H goes up when O goes up, and vice versa (directly proportional)
H = k * 1/A, H goes up when A goes down, and vice versa (inversely proportional)

H = 8, O = 6, A = 2

H = ?, O = 4, A = 4
Optimism went down so Happiness should go down
Anger went up so Happiness should go down
Happiness should be 6 (down by 2 for Optimism, and down by 2 for Anger)
