Work Step by Step

The sales of Eagles: The Greatest Hits, 1971-1975 is estimated to be 29 million. Looking at the bar graph, the bar is very close to 30 million, which suggests it is around 29 million. The sales of AC/DC: Back in Black is estimated to be 22 million. Looking at the bar graph, the bar is very close to the half-way between 20 and 25 million, which suggests it is around 22 million. Therefore, the lengths of the bars in the graph corresponds to the results obtained in Exercise 66.
