Answer

Explanation:

Step1: Define the relationship

The number of cars left ( C ) is the initial number of cars minus the number of cars rented ( R ). The initial number of cars is 15. So the equation is ( C = 15 - R ).

Step2: Evaluate for ( R = 12 )

Substitute ( R = 12 ) into the equation ( C = 15 - R ). So ( C = 15 - 12 = 3 ).

Answer:

Equation: ( C = 15 - R ) Number of cars left after renting 12 of them: 3 cars
