In a fuel station the service costs $1.75 per car, every liter of fuel costs 0.65$. Assuming that a company owns 12 cars and that every fuel tank contains 55 liters and they are all empty, how much money total will it cost to fuel all cars?

A. 320$
B. 380$
C. 420$
D. 450$
E. 480$


Total Cost = ( 1.75*12 ) + ( 0.65 * 12 * 55 ) = 21 + 429 => 450

Hence answer will be (D) 450
