Final answer:
John Smith can spend up to $200 on his car rental with a daily cost of $40 and a per mile cost of $0.50. We define x as the number of rental days and y as the number of miles driven.
Step-by-step explanation:
To address the problem at hand, we first need to define variables for the car rental scenario involving John Smith. Let x represent the number of days John rents the car, and y represent the number of miles he drives. Given that John has a budget of $200 and the costs are $40 per day and $0.50 per mile, we can establish a budget equation to demonstrate the relationship between days rented, miles driven, and the budget limit.
To write an inequality that represents this scenario:
- Cost per day: $40
- Cost per mile: $0.50
- Total budget: $200
Our inequality will be:
40x + 0.50y ≤ 200
This inequality represents the combination of days (x) and miles (y) that John can afford with his $200 budget, where he cannot exceed this amount.
