The percentage increase in the number of cars from hour 2 to hour 3 is 16.7%
<h3>How to determine the percentage increase in the number of cars?</h3>
In this question, we have the given figures that can be used in our computation:
Hour 1 = 22 cars
Hour 2 = 30 cars
Hour 2 = 35 cars
We want to calculate the percentage increase in the number of cars
So, we make use of only the following parameters
Hour 2 = 30 cars
Hour 2 = 35 cars
These figures can be represented as
Initial amount = 30
Final amount = 35
The percentage of the increase of the cars is then calculated using the following percentage equation
Increase percentage = (Final amount - Initial amount)/Initial amount * 100%
Substitute the known values in the above equation, so, we have the following representation
Increase percentage = (35 - 30)/30* 100%
Evaluate
Increase percentage = 16.7%
Hence, the increase percentage is 16.7%
