Answer:
126 people
Explanation:
The first step in this problem is to find the total number of people who were surveyed. To do so, add all the numbers in the "number" column.
45 + 25 + 15 + 5 + 10 = 100
Now, look at the number of people who said their favorite topping was pepperoni. Since there are 45, the ratio of people who like pepperoni pizza the most to total number of people is 45:100. Written as a percentage, this is 45%.
Now, find 45% of 280 because that is the number of people the question is asking about.
280 * 0.45 = 126
Therefore, you can estimate 126 people out of 280 will like pepperoni pizza the most, which means the final answer is 126.
