Answer :
[tex]To\ find\ equalibrium\ point\ we\ need\ to\ compare\ D(p)\ and\ S(p)\\\\
D(p)=S(p)\\\\
700-23p=380+17p\ \ \ |Subtract\ 17p\\\\
700-23p-17p=380\ \ \ |Subtract\ 700\\\\
-40p=380-700\\\\
-40p=-320\ \ \ |Divided\ by\ -40\\\\
p=8\\\\ \textbf{Equilibrium\ point\ is\ p=8}.[/tex]
Equilibrium point occurs when a number input for p gives the same answer for both D(p) and S(p). to find this, we set them equal to each other and solve for p.
700-32p = 380 + 17p
-380 -380
320 - 32p = 17p
+32p +32p
320 = 49p
/49 /49
p = 6.5306
700-32p = 380 + 17p
-380 -380
320 - 32p = 17p
+32p +32p
320 = 49p
/49 /49
p = 6.5306
