-An-Mei owns a business making and selling jackets. She has a fixed cost of $\$ 4500$ . It costs $\$ 85$ to produce each jacket. The selling price is $\$ 115$ per jacket. Let $x$ represent the number of jackets produced and sold and write the cost function, $C$ , and revenue function, $R$ .

A) $C ( x ) = 85 x + 4500$
$R ( x ) = 115 x$
B) $C ( x ) = 85 + 115 x$
$R ( x ) = 4500 x$
C) $C ( x ) = 85 + 4500 x$
$R ( x ) = 115$
D) $C ( x ) = 85 x + 4500 x$
$R ( x ) = 115 x$
