Question

estimate how many more black cars were sold than silver cars.
31,000
11,000
14,000
21,000

Explanation:

Step1: Estimate black - car sales

From the bar - graph, black car sales are around 36,000 (estimated by looking at the height of the bar for black cars on the y - axis labeled "Number of Cars Sold in Thousands").

Step2: Estimate silver - car sales

Silver car sales are around 15,000 (estimated by looking at the height of the bar for silver cars on the y - axis).

Step3: Calculate the difference

Subtract the number of silver cars sold from the number of black cars sold: \(36000 - 15000=21000\).

Answer:

21,000
