Final answer:
Inequality that represents the situation where the customer wants to spend $15 or less, we can write: 4.35 + 0.55m ≤ 15. This inequality states that the cost of the car service, which is the sum of the flat rate and the cost per mile multiplied by the number of miles traveled, should be less than or equal to $15.
Step-by-step explanation:
To represent the situation, we can start by writing the equation for the cost of the car service. The flat rate is $4.35, and the cost per mile is $0.55. We can write the equation as:
Cost = 4.35 + 0.55m
where m is the number of miles traveled. To find the inequality that represents the situation where the customer wants to spend $15 or less, we can write:
4.35 + 0.55m ≤ 15
This inequality states that the cost of the car service, which is the sum of the flat rate and the cost per mile multiplied by the number of miles traveled, should be less than or equal to $15.
