Together they can write a particular computer program in 17 hours. Naomi can write the program by herself in 31.04 hours. How long will it take Ricky to write the program alone? 
**
1/31.04=Naomi's work rate
1/x=Rickey's work rate
1/17=Work rate when working together
sum of individual work rate=work rate when working together
1/31.04+1/x=1/17
LCD:31.04x*17
17x+31.04*17=31.04x
14.04x=31.04*17=527.68
x≈37.58
ans:
Rickey will take 37.58 hours to write the program alone
