A bank teller has some fivedollar bills and some twentydollar bills. The teller has 10 more of the
twenties. The total value of the money is $850. Find the number of fivedollar bills that the teller
has?

N*20 + (N10)10=850
check that. 
Thanks that was all that I needed now let me work on my problem and tell if I got the correct answer.
N*20+(N10)10=850
20n+20n200+10=850
40n190=850
n=26 
That works out correctly.
26 * $5 = #130
36 * $20 = $720
130 + 720 = 850
