Thanks 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
N*20+(N-10)10=850
20n+20n-200+10=850
40n-190=850
n=26
That works out correctly.
26 * $5 = #130
36 * $20 = $720
130 + 720 = 850
26 * $5 = #130
36 * $20 = $720
130 + 720 = 850
