Total number of cars in a rally = 135 cars.
Fee paid by each driver in to participate in the rally = $25.
We are given fee for each one driver to participate in the rally and we need to find total money all drivers pay in all.
So, the total money all drivers pay in all = (Total number of cars) × (Fee paid by each driver).
The total money all drivers pay in all = 135 cars × $25
= $3375.
Therefore, $3375 the drivers paid in all.
