Call the production cost 'C', the revenue 'R' and the number of CDs 'n':

C=2000+5n
R=10n
By definition Profit P = R-C, therefore P=10n-2000+5n = 5n-2000.

Sindrei [870]

Step-by-step explanation:

$sum \: of \: interior \\ \: angels \: is \: 2340 \: degrees. \\ (n−2)⋅180=2340 \\ 180n - 360=2340 \\ 180n = 2700 \\ n=15 \\ number \: of \: sides=15$

the polygon is 15 sided.
