A <u>shift </u><u>of</u> the supply curve represents a change in supply while a  <u>movement </u><u>along</u> the supply curve represents a change in the quantity supplied.
Supply is defined in economics as the total amount of a specified product or service offered to consumers by a supplier at a specified time and price level. This is usually determined by market movements. For example, increased demand may prompt suppliers to increase supply. 
In economics, supply is the number of goods that an individual or firm makes available in the market. This refers to the amount you are producing at a particular point in time. For example, if Apple made 100 of its iPhones, that would be the product to be launched. Supply can refer to the quantity available at a particular price or the quantity available across the price range displayed on the chart.

Answer:
0.2 or 20%
Explanation:
The three possible outcomes, with respective probabilities and returns, as follows
Outcome 1: Probability (P) = 0.35, Return (R) = 0.20
Outcome 2: Probability = 0.25, Return = 0.36
Outcome 3: Probability = 0.40, Return = 0.10.
The expected return will be computed as follows.
Expected Return = 
= (0.35*0.20) + (0.25*0.36) + (0.40*0.10)
= 0.07 + 0.09 + 0.04
= 0.2
Therefore expected return = 0.2 or 20%
 
        
             
        
        
        
Alright, so we start out with $12000, and we'd add from there. Since we add 1$ for every passenger, our equation with p being the number of passengers would be 1*p (e.g. for 1 passenger we have 1*1=1, 2 passengers we have 1+1(2 times)=2). Substituting 50,000 for p, we have 1*50,000=50,000. Next, we have to add 12,000 to that (as that's a flat fee) to get 50000+12000=62000
