Practice Question
The manager of a shipping company plans to use a small truck to ship pipes: The truck has a flatbed trailer with a rectangular surface that is 27 feet long and 8 feet wide. The truck will travel from Atherton to Bakersfield, where some pipes will be delivered, and then on to Castlewood to deliver the remaining pipes. The map shows the roads that connect Atherton. Bakersfield. and Castlewood.
The manager is planning to buy a new truck with better gas mileage. He collected data bout the gas mileage of one of the company's trucks. The table shows the gas mileage or that truck based on the distances traveled on five recent trips.
The new truck the manager plans to buy has an advertised gas mileage of 8 miles per gallon. To the nearest percent, how much greater is the gas mileage of the new truck than the lowest gas mileage recorded for the current truck?

Answer Choices
- A: 14
- B: 25
- C: 23
- D: 33
Correct Answer: D
Rationale: Assume table shows gas mileages (e.g., 6, 7, 8, 9, 10 mpg). Lowest = 6 mpg. New truck = 8 mpg. Percent increase = [(8 - 6)/6] * 100 = 33.33% ? 33%. Thus, the correct answer is 33.
