Answer:
B. Compare price per unit
Explanation:
Here's how Thomas can compare the price per unit when buying a used car:
1. Calculate the Price per Unit: Thomas can divide the total cost of the used car by its mileage, age, or any other relevant unit to determine the price per unit. For example, if one car costs $10,000 and has 100,000 miles, the price per mile would be $0.10.
2. Compare Different Options: By calculating the price per unit for different used cars that Thomas is considering, he can compare them and choose the one that offers the best value. Sometimes a car with a higher upfront cost may actually be more cost-effective in the long run if its price per unit is lower.
3. Make an Informed Decision: By using the price per unit comparison, Thomas can make an informed decision based on both the initial cost and the ongoing expenses associated with the used car he is purchasing.
