**Lisa**, Thursday, September 3, 2009 at 4:26pmThanks that was all that I needed now let me work on my problem and tell if I got the correct answer.

N*20+(N-10)10=850

20n+20n-200+10=850

40n-190=850

n=26

**Ms. Sue**, Thursday, September 3, 2009 at 4:34pmThat works out correctly.

26 * $5 = #130

36 * $20 = $720

130 + 720 = 850
