Toll is $1.00 for car and driver each additional passenger is ,75 cents the toll was $3.25 how many people were riding in car?
Let's call the number of additional passengers "x".
The toll for the car and driver is $1.00, so we have: 1 + x passengers.
The toll for each additional passenger is $0.75, so the rest of the toll, $3.25 - $1.00 = $2.25, must account for the additional passengers' tolls.
We can set up the equation: 1 + 0.75x = 2.25.
Subtracting 1 from both sides, we get: 0.75x = 1.25.
Dividing both sides by 0.75, we find x = 1.67.
Since we can't have a fraction of a passenger, we have to round down.
Thus, there were 1 additional passenger riding in the car.
Adding the car driver, the total number of people riding in the car is 1 + 1 = 2. Answer: \boxed{2}.
Let's set up an equation to solve this problem.
Let's assume that the number of additional passengers in the car is represented by 'x'.
The cost for the car and driver is $1.00, and each additional passenger costs $0.75. Therefore, the total cost of the toll can be calculated using the equation:
1 + 0.75x = 3.25
Now, let's solve the equation for 'x' to find the number of additional passengers:
0.75x = 3.25 - 1
0.75x = 2.25
Dividing both sides by 0.75, we get:
x = 2.25 / 0.75
x = 3
So, there were 3 additional passengers riding in the car.
