ANSWER

EXPLANATION
The diagram represents the net of a rectangular prism.
The dimensions are,


and

The total surface area of a rectangular prism is given by:

We substitute the values to obtain,


B because the center of data is best measured by the median when there are outliers, and 42 is an outlier in this set.
To determine the number of cars that will be sold by the year 2020, we will use the equation,
N = (N1)(1 - r)^(t)
where N1 is the starting number of cars, r is the rate of the decrease, and t is the number of years from 2012. Substituting the konwn values,
N = (500)(1 - 0.028)^(8)
N = 398.38
The closest integer to the calculated value is 398. Thus, the answer is 398 cars.
