A music store sells synthesizers, violins, and saxaphones. The given bar graph shows how many of each instrument the store has. How many more synthesizers are there than violins?

Let’s begin by figuring out how many of each instrument the store has. The number of synthesizers will be 11, the number of violins will be three, and the number of saxophones will be 13.

So the question is asking how many more synthesizers are there than violins. So we are comparing these two. So to find the difference between them, we need to take 11 minus three, which is eight.

Therefore, there are eight more synthesizers than there are violins.
