The Cost of Renting a Backhoe at One Distributor Is $C ( x ) = 335 x + 35 ; \quad \$ 2,380$

The cost of renting a backhoe at one distributor is $335, plus $35 per day. Write a linear function C(x) that describes the cost of renting the backhoe for x days, then use your function to find how much it would cost to rent it for 7 days.

A) $C ( x ) = 335 x + 35 ; \quad \$ 2,380$
B) $C ( x ) = 7 ( 335 + 35 x ) ; \quad \$ 4,060$
C) $C ( x ) = 335 + 35 x , \quad \$ 580$
D) $C ( x ) = 35 x + 328 ; \quad \$ 573$
