![\bf \begin{cases} f(x)=\cfrac{1}{2}x+1\\\\ g(x)=x+2\\ g(~~f(x)~~)=\textit{selling price} \end{cases}\\\\ -------------------------------\\\\ \boxed{x=10}\qquad f(10)=\cfrac{1}{2}10+1\implies f(10)=5+1\implies \boxed{f(10)=6}\\\\ -------------------------------\\\\ g(~~f(x)~~)=[f(x)]+2\implies g(~~f(10)~~)=[f(10)]+2 \\\\\\ g(~~f(10)~~)=\boxed{6}+2\implies g(~~f(10)~~)=8](/tpl/images/0461/6768/f45fc.png)
