They are taking into account the carbon coming from the gasoline will combine with 2 molecules of oxygen in the air to produce CO2. Given the molecular weight of the Carbon + Oxygen + Oxygen they get the value that CO2 will be 3.7 times greater than the initial starting weight of Carbon in the gasoline.
