The total number of vehicles in service is found by determining the quantity of each vehicle type, calculating the out-of-service vehicles for each subgroup (26 diesel and 28 electric), and subtracting this total (54) from the overall fleet of 200, resulting in 146 active vehicles.

Instead of finding the out-of-service vehicles and subtracting, you can directly calculate the in-service vehicles. Diesel in service = 80% of 130 = 104. Electric in service = 60% of 70 = 42. Total in service = 104 + 42 = 146.
