in a fuel station the service costs $ 2.05 per car, every liter of fuel costs 0.6 $. assuming that you fill up 3 mini - vans and 2 trucks, how much money will the fuel cost to all the cars owners total, if a mini - van ' s tank is 70 liters and a truck ' s tank is 120 % bigger and they are all empty -?
add(multiply(multiply(add(70, divide(multiply(70, 120), const_100)), 2), 0.6), multiply(multiply(70, 3), 0.6))
"service cost of 3 van and 2 truck = 2.05 * ( 3 + 2 ) = 10.5 fuel in 3 van = 3 * 70 = 210 litre fuel in 2 trucks = 2 * 70 ( 1 + 120 / 100 ) = 308 total fuel ( van + truck ) = 518 litre total fuel cost = 518 * 0.6 = 310.8 total cost = fuel + service = 310.8 + 10.25 = 321.05 answer is b"
