Questions & Step-by-Step Solutions
If the average of 4 numbers is 15, what is the sum of those numbers?
Correct Answer: 60
Step 1: Understand that the average of a set of numbers is found by dividing the sum of those numbers by how many numbers there are.
Step 2: In this case, we have 4 numbers and their average is 15.
Step 3: To find the sum of the numbers, we can use the formula: Sum = Average * Number of items.
Step 4: Plug in the values: Sum = 15 (average) * 4 (numbers).
Step 5: Calculate the sum: 15 * 4 = 60.
Average and Sum Relationship – The average of a set of numbers is calculated by dividing the sum of the numbers by the count of the numbers. Therefore, to find the sum when the average and count are known, you multiply the average by the count.
