First, substitute $x = 200$ into $C(x) = 7x + 1,000$ to get $C(200) = 7(200) + 1,000 = 1,400 + 1,000 = 2,400$. Then, calculate $A(200) = \frac{C(200)}{200} = \frac{2,400}{200} = 12$.

If C(x)=7x+1,000 and A(x)=C(x)x, then if x=200,A(x)=\text { If } C ( x ) = 7 x + 1,000 \text { and } A ( x ) = \frac { C ( x ) } { x } \text {, then if } x = 200 , A ( x ) = If C(x)=7x+1,000 and A(x)=xC(x)​, then if x=200,A(x)=

$\text { If } C ( x ) = 7 x + 1,000 \text { and } A ( x ) = \frac { C ( x ) } { x } \text {, then if } x = 200 , A ( x ) =$
