Strategic Advice: You rarely need to use all of the information presented in a table to answer a data analysis question. Read the question carefully to make sure you use only what you need.

Getting to the Answer: To calculate the percentage of the vehicles for each type that has less than 50,000 miles (m < 50,000), divide the number of vehicles of that type with less than 50,000 miles by the total number of vehicles of that type.

A: 2-door car = 9 ÷ 48 = 0.1875

B: 4-door car = 16 ÷ 98 ≈ 0.1633

C: SUV = 19 ÷ 94 ≈ 0.2021

D: Truck = 12 ÷ 60 = 0.2

Choice (B) is correct because 16.33% is a lower percentage than any of the other types of vehicle.
