An equivalent expression would be s+15 
You simplify the expression.
So yea the answer is s+15
        
                    
             
        
        
        
Answer: The required expected value is $3.46.
Step-by-step explanation:
Since we have given that 
Number of value of 4 or less are 
2,3,4 
So, there are 12 in numbers.
So, probability would be 

Since Aces are considered as the highest card in the deck.
So, remaining probability would be 

Amount paid or value of 4 or less = $165
Amount not paid for other case = $45
So, the expected value would be 

Hence, the required expected value is $3.46.
 
        
             
        
        
        
If

then

The ODE in terms of these series is



We can solve the recurrence exactly by substitution:


So the ODE has solution

which you may recognize as the power series of the exponential function. Then
