A car used 50 liters of gasoline and traveled a total distance of 350 km. The car's fuel efficiency is 4 km per liter on the highway and 2.5 km per liter in the city. The variable z will represent the number of liters used on the highway. Which equation could be used to find z? OA. 4z +2.5(50 - h) = 350 OB. 2.5(50-z) + 4z = 350 OC. 2.5(50 + h) + 4z = 350 O D. 4z + 2.5(50 + z) = 350
