Answer:
FV= $137,440.62 
Explanation:
Giving the following information: 
Bob makes his first $ 800 deposit into an IRA earning 7.4 % compounded annually on his 24th birthday and his last $ 800 deposit on his 39th birthday (16 equal deposits in all). With no additional deposits, the money in the IRA continues to earn 7.4 % interest compounded annually until Iob retirees on his 65th birthday.
First, 16 years:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {800*[(1.074^16)-1]}/0,074= $23,067.90
Next 25 years. 
FV= PV*(1+i)^n
FV= 23,067.90*(1.074)^25= $137,440.62 
 
        
             
        
        
        
Answer:
Loss of $397,100

Total loss = 10 contracts * 1000 barrels * loss of $39.71 per barrels = 
= 10*1000*$39.71 = $397,100
