Answer:
40
Explanation:
Reading a bar graph can give us information about the number of people within specific groups.
Reading the Graph
The most important part of this question is correctly reading the graph. First, we need to find out how many people prefer English. The bar for English is the farthest to the right. This bar has about 50 people.
Next, find the number of people that prefer History. This bar is just to the left of English. It has about 10 people.
We can tell which bar is which from the labels on the x-axis. The y-axis tells us the number of people in each bar.
Answering the Question
We are asked how many more people prefer English to History. So, we need to subtract the people that like History from the people who like English.
This means that 40 more people like English than History.
