The total area available for cars to park will be 858m².
<h3>How to calculate the area?</h3>
The area of the parking lot will be:
= 78 × 19
= 1482m²
The area of aisle will be:
= 8 × 78
= 624m²
The available area will be:
= 1482m² - 624m²
= 858m².
The compact parking spaces that will fit in the lot will be:
N × 12.5 = 858
N = 858/12.5
N = 68
The non compact parking spaces that will fit in the lot will be:
N × 16.5 = 858
N = 858/16.5
N = 52

First we can figure out an hourly rate at which cars are washed. To do so, we need to divide 5 cars by 3 hours.
Then we need to multiply 7.5 hours by the rate. This will tell us how many cars are washed in 7.5 hours.

= 12.5 cars
