Answer:
Gross Domestic Product 
= $500 
<em>GDP is the final value of goods and services. The haircut is valued at $500 so is GDP. </em>
Net National Product:
= GDP - Depreciation
= 500 - 80
= $420
National Income 
= $420
<em>This is the income that a resident of the country earns and $420 is what Barry earned in net income.</em>
Personal Income
= National income - Retained earnings
= 420 - 120 - 50
= $250
Disposable Personal Income (Dollars)
= Personal income - income taxes
= 250 - 90
= $160
 
        
             
        
        
        
In classical conditioning, the Neutral Stimulus (NS) becomes a Conditioned Stimulus (CS) after it reliably signals the impending occurrence of the Unconditioned Stimulus (US).
The conditioned stimulus (CS) is a neutral stimulus (NS) that - after being repeatedly presented before the unconditioned stimulus - evokes a similar response as the unconditioned stimulus (US).
For example, a cat staring at a can of food (unconditioned stimulus) reacts differently to the sound of a can opener being struck on any surface (neutral stimulus). But if you condition a cat to believe that striking a can opener on any surface signals it will eat a can of food, the neutral stimulus becomes the conditioned stimulus.
