William washes cars as a side job. He typically spends 4 minutes washing a car’s windows, 7 minutes washing the car body, 4 minutes cleaning the tires, and 9 minutes waxing the car. This morning he washed 2 normal cars and one big SUV, which took twice as long as a normal car. How many minutes did William spend washing all the vehicles? Let's answer step by step:

William spends 4 + 7 + 4 + 9 = 24 minutes washing a normal car. He washed 2 normal cars, so he spent 24 * 2 = 48 minutes on the normal cars. He took twice as long as one car for the SUV, so he took 24 * 2 = 48 minutes on the SUV. Thus, William spent 48 + 48 = 96 minutes washing all the vehicles. The answer: 96.
