writing and evaluating a function that models a real-world situation: basic
martina has 15 cars available to rent.
let c be the number of cars she would have left after renting r of them.
write an equation relating c to r. then use this equation to find the number of cars she would have left after renting 12 of them.
equation:
number of cars left after renting 12 of them: cars

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
