Question

You have a dataset that includes the percentage of people who prefer different types of beverages.

If there are 500 people in the dataset, and 30% of them prefer coffee, how many people prefer coffee?

Answer 1

To find out how many out of 500 people prefer coffee when 30% have that preference, convert the percentage to decimal form (0.30) and multiply by the total number (500), resulting in 150 people preferring coffee.

Step-by-step explanation:

If there are 500 people in the dataset, and 30% of them prefer coffee, the number of people who prefer coffee can be calculated as follows:

1. First, convert the percentage to a decimal by dividing it by 100. So, 30% becomes 0.30.
2. Next, multiply this decimal by the total number of people in the dataset to find out how many people prefer coffee. Therefore, 0.30 multiplied by 500 equals 150.

This means that out of 500 people, 150 people prefer coffee. This is a straightforward example of calculating a percentage of a given quantity, which is a common task in mathematics.
