Final answer:
Mr. Chen spent a total of $1012 on the 4 custom wheels for his car by multiplying the cost of one wheel ($253) by the number of wheels.
In the case of Marvin seeking a used car, he should examine vehicle history and maintenance records to determine which car offers the best value.
Step-by-step explanation:
Mr. Chen bought 4 new custom wheels for his car, with each wheel costing $253. To determine the total cost of the wheels, we need to multiply the cost of one wheel by the number of wheels.
- Multiply the cost of one wheel by the number of wheels: $253 × 4.
- Calculate the result: $253 × 4 = $1012.
So, Mr. Chen spent a total of $1012 on the custom wheels for his car.
As for the scenario about Marvin shopping for a used car, if both cars seem very similar in terms of mileage, exterior appearances, and age, Marvin should look closer into the details such as vehicle history, maintenance records, and potentially hidden costs before making a decision purely based on price.
It's possible the more expensive car has advantages not immediately apparent, such as better maintenance or a warranty, that could justify the extra cost. Otherwise, without any additional information, the cheaper option would be the most economical choice.
