Solve the Problem $C ( x ) = 10 x + 26$

Solve the problem.
-You invested $16,000 and started a business selling vases. Supplies cost $10 per vase and you are selling each vase for $26. Let x represent the number of vases produced and sold and write the cost function, C, and revenue function, R.

A) $C ( x ) = 10 x + 26$
$R ( x ) = 16,000 x$
B) $C ( x ) = 10 x + 16,000$
$R ( x ) = 26 x$
C) $C ( x ) = 10 x + 16,000$
$R ( x ) = 26$
D) $C ( x ) = 10 x + 16,000 x$
$R ( x ) = 26 x$
